After installing patch having problems reinstalling

[Cethlion]

I installed patch 1.7 not realizing that it was not that right one. So I uninstalled Kings Bounty and was going to reinstall to get rid of the patch, but I have been having many problems with the reinstall.

For some reason when I try to reinstall it will sometime freeze while installing, other times my whole computer will freeze. Other times it will give an error saying it could not find a file on the disc. It got to 70 percent one time then restarted my computer for some reason. Theres others but you should get the point.

I am running vista and I installed it the first time with no problems. I am thinking it must be the patch, when I uninstalled Kings Bounty it didn't get rid of all of the patch.
