Hello !

I have wirtten a little Programm in VB 4.0 (16 and 32 BIT). After
finishing it i have made an installation-programm with the
Installationwizzard of VB. But I have find out that the SETUP-Programm
(made by VB not by me) didn't work on some systems.
The SETUP Programm can't find some dlls like msvcrt.dll aso.

The Setup Programm is responsible for copying the dll files to the
System - but it should run without any dll, shoudn't it ?

What is wrong with my setup programm !

(on some W95/NT Systems the programm runs clearly - and on some other
systems the SETUP.EXE (made by VB) can't start !

Please HELP !!!

THANKS

PRB: "Unexpected error; quitting" Installing VB4 Application

Article ID: Q162518
Creation Date: 22-JAN-1997

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.
