Problems with FM20.dll and crystl32.ocx while opening VB6 project

Question

A client has recently given me some work involving their (old) VB6 program. I've successfully installed VB6 in a VM with Windows XP (32 bit), and it works just fine. The problem is when I try to open the client's program. The following messages pop up:

crystl32.ocx could not be loaded--Continue Loading Project?

FM20.DLL could not be loaded--Continue Loading Project?

After that there are a bunch of warnings cause of crystl32.ocx. So I tried to register the dependencies with regsvr32, but it said that the modules couldn't be found, even though they were right there. Googling the problem took me to download Dependency Walker and find which dll files were needed for those files, which were:

msvcr100.dll

IEShims.dll

wer.dll

crpe32.dll

After downloading these dll files, I tried registering the first one, but it said that the "dllregisterserver entry point was not found". So I tried to unregister it first, but it couldn't find the module.

I've reinstalled VB6 several times, to no effect. Any ideas on how to make this work?

Answer 1

Crystl32.ocx and Crpe32.dll are Crystal Reports run time files.

FM20.DLL is Microsoft Form 2.0 Library with some standard GUI controls like label, text box, check box etc. Msvcr100.dll is a part of MS Visual C++ 2010 Redistributable Package

If there is an installer of your client's program you should run it before opening the source code with VB6 IDE. That way you’ll get all the dependencies required by VB6 program. If not, please post the vbp file of your VB6 application.
