trouble uninstalling games

I have Windows XP Home with service pack 3. I installed Hidden Mystery Civil War and Hidden Mystery Buckingham Palace from a single disk. I want to uninstall them and get them off my computer but I get a message that WISEInstall cannot open the install log. How can I get the game off my system. I am having trouble with my system running very slow and my cursor acts like it is having a breakdown when I try to use any other program and before I installed the game I never had this problem so I am sure the game is the culprit. I can't open the WISE log even from Windows Explorer. I have scanned the game folder and did another scan on my entire system and no virus or malware or anything like that was found.

 

I will keep that one in mind next time I have problems. My recent one was so bothersome I couldn't get my sign in screen for Yahoo on my desktop to load up. So I read the posts here when it finally let me on and I found one saying to delete the game's files. I knew that was last resort stuff but had reached that point, so I deleted all files with the name of the game or game company in them and now my computer is back to normal. The Revo Uninstaller will probably be much faster so I will remember it. I play a lot of simple little pc games on my computer with my five year old when it is raining or too hot to go outside. Thanks for the info.
