Help with Instalation of Program

I was wondering if anyone could help me with a small problem I have with a program?
I am trying to install a program (AMOS) and it keeps telling me I need to have Service Pack 3 or higher installed on the system.
I use Win 2K with SP1. I have been to the programs website and it states that the version I am attempting to install should work with W2K.
My Question is:
Does anyone know how to fool a program into believing the OS is different to what is actually there.
I need the program to complete some research for my honors thesis.
Thanks for any help!

Get the latest application compatibility from Microsoft. After you run it, then create a shortcut on your desktop for the application that you are trying to run. For eg: The application has a setup program that fails when you run it. Create a shortcut to the setup program. Right click on the shortcut and go to properties. One of the tabs will say compatibility. Choose Win95, Win98 or NT 4.0. If it then installs fine, great, have a nice day. If it doesn't, then I am out of suggestions.

Thanks Em for your advice. I knew I could change the compatibility somehow but I had forgotten it was that easy.
I managed to get teh program installed but it still won't run. Keeps looking for files that are there but can't find them. I think they are located in a different directory or it is still having some version conflicts!
Once again thanks for the help and advice.
