         FIELD OF INVENTION  
         [0002]    The present invention generally relates to the field of software installation. More specifically, an embodiment of the present invention provides a multi-platform, efficient, and lightweight installation solution, for example, for installing software applications on a computer system.  
         BACKGROUND OF INVENTION  
         [0003]    In today&#39;s computer systems, applications are generally utilized to manipulate data. For example, a Web browser can enable a user to access data on the Internet. The data may include text, graphics, video, sound, and the like. To provide access to an application, that application must first be installed on either a stand-alone computer, or a server accessible through a network, for example. Today&#39;s installer applications, however, often require users to close all other running applications before the installation can proceed. One reason for such restriction is to ensure that the installer does not face any shortage of computer resources.  
           [0004]    This restriction, however, limits software designers in that information displayed to users during the installation will have to be incorporated into the installer application. This approach not only limits a software engineer who is designing an installer, but also extends the period for designing such installers. More specifically, the installer code will have to include not only the installation code, but also the data and code for displaying the desired information during the installation.  
           [0005]    The problems associated with the prior art are exasperated even more for multi-platform installers. In particular, when a software engineer is designing a multi-platform installation product (i.e., an installer that can install an application on multiple platforms), he/she will have to take into account unique implementation issues associated with launching other applications during the installation. For example, launching an external application while installing a software program on a computer running a UNIX operating system may require different commands than launching the respective version of the external application in the Microsoft Windows environment.  
         SUMMARY OF INVENTION  
         [0006]    The present invention, which may be implemented utilizing a general-purpose digital computer, in certain embodiments, includes novel methods and apparatus to provide efficient and/or lightweight software installation. In an embodiment, a method of configuring a software installer is disclosed. The method includes: launching the software installer; receiving a request to launch a file while the software installer is running; the software installer accessing an application launch facility to determine a launching command for launching the file; executing the launching command to obtain an installation key; and the software installer installing a software product based on data provided by the installation key.  
           [0007]    In a further embodiment, a method of installing a software application is disclosed. The method includes: launching an application installer to install the software application; while the application installer is installing the software application, receiving information about a file to launch during the installation of the software application; determining a launching application that can launch the file; requesting a launching command from an operating system, the application installer running on the operating system; and launching the application to open the file.

       DETAILED DESCRIPTION  
       [0013]    In the following description, numerous details are set forth. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without these specific details. In other instances, well-known structures, devices, and techniques have not been shown in detail, in order to avoid obscuring the understanding of the description. The description is thus to be regarded as illustrative instead of limiting.  
         [0014]    Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least an embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.  
         [0015]    Also, select embodiments of the present invention include various operations, which are described herein. The operations of the embodiments of the present invention may be performed by hardware components or may be embodied in machine-executable instructions, which may be in turn utilized to cause a general-purpose or special-purpose processor, or logic circuits programmed with the instructions to perform the operations. Alternatively, the operations may be performed by a combination of hardware and software.  
         [0016]    Moreover, embodiments of the present invention may be provided as computer program products, which may include machine-readable medium having stored thereon instructions used to program a computer (or other electronic devices) to perform a process according to embodiments of the present invention. The machine-readable medium may include, but is not limited to, floppy diskettes, optical disks, compact disc-read only memories (CD-ROMs), and magneto-optical disks, read-only memories (ROMs), random-access memories (RAMs), erasable programmable ROMs (EPROMs), electrically EPROMs (EEPROMs), magnetic or optical cards, flash memory, or other types of media or machine-readable medium suitable for storing electronic instructions and/or data.

Accordingly, herein, a carrier wave shall be regarded as comprising a machine-readable medium.  
         [0018]    [0018]FIG. 1 illustrates an exemplary computer system  100  in which the present invention may be embodied in certain embodiments. The system  100  comprises a central processor  102 , a main memory  104 , an input/output (I/O) controller  106 , a keyboard  108 , a pointing device  110  (e.g., mouse, track ball, pen device, or the like), a display device  112 , a mass storage  114  (e.g., a nonvolatile storage such as a hard disk, an optical drive, and the like), and a network interface  118 . Additional input/output devices, such as a printing device  116 , may be included in the system  100  as desired. As illustrated, the various components of the system  100  communicate through a system bus  120  or similar architecture.  
         [0019]    In an embodiment, the computer system  100  includes a Sun Microsystems computer utilizing a SPARC microprocessor available from several vendors (including Sun Microsystems of Palo Alto, Calif.). Those with ordinary skill in the art understand, however, that any type of computer system may be utilized to embody the present invention, including those made by Hewlett Packard of Palo Alto, Calif., and IBM-compatible personal computers utilizing Intel microprocessor, which are available from several vendors (including IBM of Armonk, N.Y.). Also, instead of a single processor, two or more processors (whether on a single chip or on separate chips) can be utilized to provide speedup in operations. It is further envisioned that the processor  102  may be a complex instruction set computer (CISC) microprocessor, a reduced instruction set computing (RISC) microprocessor, a very long instruction word (VLIW) microprocessor, a processor implementing a combination of instruction sets, and the like.  
         [0020]    The network interface  118  provides communication capability with other computer systems on a same local network, on a different network connected via modems and the like to the present network, or to other computers across the Internet. In various embodiments, the network interface  118  can be implemented utilizing technologies including, but not limited to, Ethernet, Fast Ethernet, wide-area network (WAN), leased line (such as T 1 , T 3 , optical carrier  3  (OC 3 ), and the like), analog modem, digital subscriber line (DSL and its varieties such as high bit-rate DSL (HDSL), integrated services digital network DSL (IDSL), and the like), cellular, time division multiplexing (TDM), universal serial bus (USB and its varieties such as USB II), asynchronous transfer mode (ATM), satellite, cable modem, and/or FireWire.  
         [0021]    Moreover, the computer system  100  may utilize operating systems such as Solaris, Windows (and its varieties such as CE, NT, 2000, XP, ME, and the like), HPUX, IBM-AIX, PALM, UNIX, Berkeley software distribution (BSD) UNIX, Linux, Apple UNIX (AUX), Macintosh operating system (Mac OS) (including Mac OS X), and the like. Also, it is envisioned that in certain embodiments, the computer system  100  is a general purpose computer capable of running any number of applications such as those available from companies including Oracle, Siebel, Unisys, Microsoft, and the like.  
         [0022]    [0022]FIG. 2 illustrates an exemplarily block diagram of an installation method  200  in an accordance with an embodiment of the present invention. The installation method  200  includes a set of installer build steps  202  and installer execution steps  204 . The installer built steps  202  includes a step  206  which determines the file name of a file to be launched. In an embodiment, this file information may be embedded in the installer being built. In a step  208 , a registry service is added to the installer. It is envisioned that the registry service added may depend on the operating system utilized for the application being installed. For example, in a Windows environment, the registry service may be Win32. Similarly, in the Solaris environment, the registry service may be the common desktop environment (CDE), and in a Mac OS, it may be the launch services.  
         [0023]    In a step  210  (the first step of the installer execution steps  204 ), the registry service of the step  208  is instantiated. A step  212  determines the extension of the filed of the step  206  to be launched. A step  214  looks up the value or identity of the appropriate application for launching the file of the step  206 , for example, based on the determined extension of the step  214  (e.g., the application that is identified by the registry service of the step  208  for launching the file of the step  206 ). For example, in the Windows environment, the step  214  would look up the default value of the HKEY_CLASSES_ROOT\.XYX in the Win32 registry. In an embodiment, the step  214  is envisioned to yield the application name (e.g., ApplicationX).  
         [0024]    A step  216  looks up the value or command for opening the application identified by the step  214 , for example, with reference to the registry service of the step  208 . For example, in the Windows environment, the step  214  would look up the default value for the HKEY_CLASSES_ROOT\ApplicationX\shell\open\command utilizing the registry service of the step  208 . The step  216  is envisioned to yield the launch command (e.g., launch.exe). In a step  218 , the launch command is cleaned up, for example, by removing quotes and/or extraneous variables (such as DOS variables that may be present in a Windows environment embodiment). In a step  220 , the file name of the file to launch is appended to the launch command (e.g., by appending the file name of the step  206  to the launch command of the step  216  and/or  218 ).  
         [0025]    In a step  222 , the launch command and the appropriate launch arguments are saved (optional), for example, to a property. In an embodiment, the property is generally considered as a temporary placeholder for the complete launch command. A step  224  calls the execution facility on the saved launch command or property containing the launch command (and where applicable launch arguments). For example in the Windows environment, the execution facility may be the execution wizard. In a step  226 , the actual application is launched which, for example, can in turn display the file determined in the step  206 .  
         [0026]    Accordingly, the installation method  200 , in an embodiment, may provide for a multi-platform solution for building and executing an installation program capable of launching files which need to run through an external application program. In this fashion, the installation method  200  may avoid requiring a software engineer to take every unique implementation issue associated with launching other applications during the installation process, especially for a multi-platform installation solution. Also, such embodiments may reduce the period required for designing multi-platform installers.  
         [0027]    [0027]FIG. 3 illustrates an exemplarily installer configuration method  300  in accordance with an embodiment of the present invention. The installer configuration method  300  in a step  302  launches an installer. It is envisioned that the installer may be launched by a user or alternatively automatically, for example, via a timer or by other computer applications. In a step  304 , the launched installer may launch an external file such as a hypertext markup language (HTML) page by, for example, utilizing a Web browser (such as the Internet Explorer available from Microsoft Corporation of Redmond, Wash., and Netscape Navigator available from various sources including iPlanet, now a division of Sun Microsystems, Inc., of Palo Alto, Calif.). In an embodiment, it is envisioned that the step  304  may be performed by utilizing the steps discussed with respect to FIG. 2.  
         [0028]    In a step  306 , the launched HTML page(s) of the step  304  may require a user to provide information about the user. In an embodiment, the user information may include a unique identifying indicia (e.g., a serial number, authorization number, etc.), contact information (such as address, name, phone number, etc.), operating system used, preferred language, and the like. Based on the captured information in the step  306 , an installation key may be provided in a step  308 . In one embodiment, the installation key is envisioned to include information utilized by the installer to provide an appropriate set of features for the application being installed. For example, the user may request that features from multi-user application installation be utilized, a less resource intensive version of the application be installed (for example, for a portable and/or handheld device), duration of the application being accessible (for example, where a user may only want to utilize a tax software for a month before the tax filing deadline), the application to be localized into the user&#39;s preferred language, a user identity and/or password be assigned for accessing the application, select a hostname/machine identity of a machine the application is allowed to run on (for example, to protect intellectual property), and the like. In a step  310 , the installation key may be validated. It is envisioned that, in an embodiment, the validation may be performed by the installer launched in the step  302  (e.g., by utilizing encryption, hash tables, public-private key pairs, and the like).  
         [0029]    Alternatively, in an embodiment, the validation may be performed by a remote service. Storing the validation information in a remote service configuration may enhance security in an embodiment. In a step  312 , the appropriate components are installed, for example, based on information associated with or contained in the installation key. The components to be installed may reside on a local storage device (such as a CD-ROM) and/or on a remote Internet and/or intranet server such as those discussed with respect to FIG. 1.  
         [0030]    In one embodiment, the installation software may be distributed to users (or potential users) free of charge. It is also envisioned that in the step  308  the key may be displayed on the screen to a user which, in turn, may have to enter the key manually into the installation software. In one embodiment, the step  304  may be accomplished by asking a user to call a toll-free number or another appropriate number and discuss the installation options with a customer service or sales associate. One form of captured user data in the step  306  may be geographically based. For example, a user in Chicago may receive map information that is pertinent to the geographical location of that user (i.e. the Chicago vicinity). It is further envisioned that in an embodiment the installer may launch a presentation during the installation through, for example, QuickTime provided by Apple Computers of Cupertino, Calif., and/or Real Player provided by RealNetworks, Inc., of Seattle, Wash.  
         [0031]    In a further embodiment, after the installation is complete, the installer software may launch the newly installed application. It is envisioned that in another embodiment if the installer faces an error or detects an error, the installer may launch an error reporting application such as an electronic mail (Email) application to send an Email to the relevant party (e.g., a product support group). In Windows environment, the error reporting application may be the designated/default Email application. The installer may also send a portion of an error log with through the error reporting application (in the case of an Email, as an attachment and/or an inline text message).  
         [0032]    In one embodiment of the present invention, it is envisioned that an open application programming interface (API) may be utilized to build an installer. Also, the API may be implemented in the Java programming language. In another embodiment of the present invention, the installation key may have a termination date, i.e., a user will have to utilize the installation key within a certain amount of time (for example ten days).  
         [0033]    The foregoing description has been directed to specific embodiments. It will be apparent to those with ordinary skill in the art that modifications may be made to the described embodiments, with the attainment of all or some of the advantages. For example, the techniques of the present invention may be utilized for provision of advertisement, messages, software customization, market research, protection of intellectual property including copyrightable material (e.g., by encrypting the software key, for example, with the hostname of the target machine, so the installed software only runs on that specific machine), and the like. Therefore, it is the object of the appended claims to cover all such variations and modifications as come within the spirit and scope of the invention.
