Please Help!

I recently purchased InstallShield Express 2 and have downloaded the
isx2.exe update. I have installed my program many times under Win95
operating system using InstallShield.

I have gotten an Unexpected Error on two different occasions after
installation of my software using Installshield. After
what appears to be a clean installation and the system is rebooted
and the program is kicked off this error occurs.

My program is written in VB with Access database. Can someone give me
some ideas of why it is not working. I would think that all the dll
are self registering if I'm using VB.

thanks
Larry

Larry,

It appears that this may be a Visual Basic error.
If you are including any OLE files with your installation? There is a conflict when installing
OLEPRO32.DLL on systems with a different version of OLE. Please take a look at the enclosed
article from the Microsoft Knowledge Base. Let me know if you have any questions. In addition to
the work-arounds suggested in the article, you could also include the file OLEAUT32.DLL with your
setup since InstallShield is capable of rebooting the target
machine.

PRB: "Unexpected error; quitting" Installing VB4 Application

Article ID: Q162518
Creation Date: 22-JAN-1997
Revision Date: 25-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.
