As I want to share with a friend of mine the benefit of a program I wrote, I prepared a set of diskettes using VB4 Application Setup Wizard (he has no VB installed and no MS Access either). I had the chance to install the four diskettes on his main PC (a simple clone) and everything went OK. But, installing the same four diskettes on another PC (Packard Bell) with Win95 and nothing else installed on it, I got a message saying "Error registering TABCTL32.OCX" and some other OCXs like GRID32, etc.
I'm not able to go on due to the fact that
1. Windows95 registry is a living mistery (al least for me) and
2. with the same operating system (even with a different Service Release) everything is performed correctly

I suspect there is an Hardware compatibility problem...but how can I be sure of it ?

Can anybody help me ??
Thanks in advance
