I just moved GIF Animator 5.00(2001) and 5.05(2002) from my W2K box to my Windows 7 Home Premium laptop and both initially appear to work fine. I have not attempted any extensive operations.
I'm running compatibility as on Windows XP (SP3)...
The trick is to copy the complete directory to the target computer.
I did not try this on Vista...
Essentially GA is a stand alone program once you have an installation it will run most anywhere.
