Agree with RealHeavyDude, it´s a matter of files or paths that doesn't exist.
When we used Windows XP, the progress path was "c:\archivos de programa\progress\".
We had the same error message tan you when we moved to Windows 7, and simply copied the links. But the path was now "C:\Program Files\Progress\" or, in some cases, "C:\Program Files (x86)\Progress\"
The solution was editing the links and the .INI files.
