button not working (WNT)

[StevoC]

We have a home grown application here written in either VB or VC++. When a user tries to install, the program asks the user where they want to install the program. The user clicks a BROWSE button and (it looks like) explorer takes over and the user can navigate to the directory of chioce for install. This process works on all PC's tried except one. Would anyone be able to point me in the right direction of where to look in the NT OS directory to check dll's, etc. The program was written long ago and the code is not available. Also, it doesn't work even if you're logged in as an admin. You click the button and it's as if there is no code behind it, nothing happens.

Running:
Windows NT 4.0 with SP6

Help is appreciated.

In version 6 of VB I believe the drive list box is a standard VB control contained in the visual basic run time dll (msvbvm60.dll). I'm not sure if this has always been the case. I did a search on my drive and also found a msvbvm50.dll. This may help as a starting point by comparing these files with a unit that is working.

I checked a working one with the non-working one, and they both have the file you mentioned, even the one you have.

msvbvm50.dll & msvbvm60.dll appear and are the same versions.

Anyone have any other suggestions? I am so not the programmer type. Thanks for the previous suggestion.
