>Hi,

>Keith Chisarik here from Sigma Data Systems Inc. I have written an application in VFP 6.0, I am at the stage where I'm making install disks. This process went well for a Win 95/98 target using WiseInstaller 8.03, however, when I changed the install script to install my required dll's in the windows\system32 directory of the NT target machine instead of the windows\system directory all kinds of bad things happen. The install program correctly copies the dll's and ocx's to Winnt\system32 but during the registration process many many errors are reported. The end result if the test machine wont even boot. Any insights you have on what I may be doing wrong will be GREATLY appreciated. I was under the impression that the only difference between a 95/98 install and a NT install was the correct system directory for dll's, ocx's, etc. MANY THANKS IN ADVANCE.

Different shell components are used by NT and Win9x - you need to ensure that the shell components are added to the system through the appropriate NT Service Packs; blind copy of Win9x components is almost certain to fail.

The CreateToolhelp32Snapshot API is not available at all under NT; Win9x and Win2K, and I'm not certain all versions of Win95 support it. You have to use different mechanisms to check for running processes under NT.

You're going to need to make a lot of adjustments to your install if you based the file requirements on Win9x; it'll probably have trouble with Win2K as well, and possibly ME.

FWIW, the shell components you're adding for Win9x won't behave with Win95 Retail versions that do not have the Active Desktop components installed via IE4, either. The install is seriously faulty.
