PRB: "Unexpected error; quitting" Installing VB4 Application
Last reviewed: January 25, 1997 
Article ID: Q162518 The information in this article applies to: 
•Standard, Professional, and Enterprise Editions of Microsoft Visual
Basic, 32-bit only, for Windows, version 4.0 on the following
platform: x86 
SYMPTOMS
When you attempt to install a Visual Basic 4.0 32-bit application
created using the Setup Wizard, the following error message appears: 
   Unexpected Error; Quitting
CAUSE
This problem occurs because the target machine has version 5.x of
Olepro32.dll installed but does not have version 2.20.xxx of
Oleaut32.dll installed. This can happen when Visual Basic 4.0
developers install an Office 97 application, Internet Explorer 3.0, or
Visual Basic 5.0 on their machine (thus installing Olepro32.dll
version 5.x), and then create a distribution using the Visual Basic
4.0 Setup Toolkit. The Visual Basic 4.0 Setup Toolkit includes version
5.x Olepro32.dll in the files it installs. When an attempt is made to
install the Visual Basic 4.0 application on a machine that does not
have the version 2.20 Oleaut32.dll, it fails as described above,
leaving the updated version of Olepro32.dll on the target machine. 
Also, any application on the target machine that uses Olepro32.dll
will no longer work because Olepro32.dll attempts to forward calls
into the new Oleaut32.dll, which is not present. 
RESOLUTION
The Visual Basic 4.0 Setup Toolkit cannot be used to install the
updated Oleaut32.dll on the target system because doing so requires
the system to be restarted and the Visual Basic 4.0 Setup Toolkit does
not have this capability. 
To correct problems on target machines where installation was
attempted, there are two options: 
1.Install an application that includes the new Oleaut32.dll onto the
problem machines by installing any of the following apps: Internet
Explorer 3.0 or Visual Basic 5.0 CC edition (downloadable from the
Web), Office 97, Visual Basic 5.0, Windows NT 4.0, or Windows NT 3.51
Service Pack 5. 
2.Get the original Olepro32.dll from the Visual Basic 4.0 operating
system CD-ROM and replace the 5.x version of Olepro32.dll with it.
Machines that are not having problems do not need to delete any files.
You now need to recreate your installation so the problem will not
re-occur. Do this by copying the following components from the
\vb\system directory of your Visual Basic 4.0 CD-ROM: 
   OLEPRO32.DLL
   MFC40.DLL
   MSVCRT40.DLL
to the following folder: 
   C:\Program Files\Microsoft Visual Basic\Setupkit\Kitfil32\sys32
Now recreate your distribution. Microsoft Visual Basic 4.0's Setup
Wizard always looks first at the above folder when searching for
dependent files. When you install your application, only less-recent
files on the target machine will be overwritten. 
STATUS
Microsoft is researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.

ERRORE IMPREVISTO! L' ESECUZIONE VERRA' TERMINATA
  In comp.lang.basic.visual.misc avevo letto che nella knowledge base
c'e' la spiegazione di questo problema. Non so se ci sia anche la
soluzione.
