Once you have selected the location for the file, Netscape downloads it. If it is a Zip file, Netscape will run the file decompression program to decompress it. At this point, you have on your disk an installable copy of the program. The next step is to run the installation program. In the case of a Zip file, once it is unzipped, you need to find the installation, normally setup.exe or install.exe will start the installation process.
Self extracting archives normally launch the installation program automatically.
If not, look in the location where you ran the self extracting archive for a program named setup.exe or install.exe. If you have downloaded a file and never noticed where it is being stored it can be found. The easiest way to find a file that you have downloaded is by running the file find. To do this click on start, then find. You can also search for the date, this will bring up files that have the current date associated with them.
