>I'm trying to support an existing app on an NT network while I'm upgrading it to Visual 5. Several users report being unable to install the app, which installs fine in Windows 3.x. Does anyone have experience with this?

I run 2.6 app over WindowsNT network from Win95 workstations. Problems arise if I try to run it from WinNT workstation. What kind of installation problem your users have? Basically, 2.6 installation is just copying of exe and esl files.
