I have a program that installs and runs file on Windows XP, Windows Vista, and Windows 7. It appears to run without on problems on those operating systems whether or not they are 32bit or 64bit. But, this program will not run on Windows 2008 R2. For some reason, I get an error message saying that a DLL for that program cannot be found; however, that DLL is in the install directory and I even put the path to that program in my system path. No joy.
Where should I look in troubleshooting this? We have developed the program ourselves so we can't really ask the developer lol.
By default, Windows 2008 Server 2008 R2 had us install into the C:\Program Files (x86) path because it is 32bit. For other information, I am also logged in as the Administrator. Lastly, I don't think there is any UAC protection (does that exist on 2008 R2?).
If you have an idea what could cause this I would appreciate your feedback.
