Can't install 2.5, dagnabit.

I am running sp3 and can not update to 2.5. I removed the previous version of Hog 3 PC using the MS uninstall tool, as described in the technote. When I try to install 2.5 it goes through all the motions until the end of the process when it says it is "rolling back action" and then does not "alter my system."

I tried taking my system back to sp2, reinstalling and then uninstalling hog 3 pc (version 2.4). And then reinstalling sp3. And then reinstalling hog 3 pc 2.5 with the same bitter results. What a huge waste of time.

At the moment the only versions of hog 3 pc I can run on this machine are very old and from the disks I got with my system.....version 1.4.

Can anyone think of something else to try, short of reinstalling windows altogether ?

thanks for your thoughts,
