install GroupWise in Windows 2000 Wkstn.

I have a new machine loaded with Windows 2000 Professional. I install Novell’s client for NT 4.81. I am trying to install Novell’s GroupWise 5.5 on the system. Installing it as a Standard Install. I am not installing Windows Messaging. However, everytime I install GroupWise it appears to be fine, until I run the program. I get a message that says that GroupWise was not install correctly and to try installing it again. 5 times and still I get that message. Does Windows 2000 have any compatibility issues with Novell GroupWise 5.5 or does someone know how to install it on Windows 200.

Thanks,
Jim
