install problem

Have downloaded latest shareware version and installed but get the following error when loading the application:
"the procedure entry point SetMenuInfo could not be located in the dll User32.dll"
Am unable to load the application.
In fact during the install I got a message dialogue box telling me to make sure I closed cam2pc to continue installing, even though I had not installed the programme.
I am running WindowsNT4.0 - maybe cam2pc is not compatable with this OS.
Anyone any ideas to resolve this problem - would be appreciated
