You need to add the following key to your regkeys.txt file to prevent it from being removed. 



1)Go to the install folder for the application, typically c:\program files\ontrack or vcom\systemsuite or fix-it 
2)Locate the file regkeys.txt 
3)Open this file in notepad 
4)Add the key listed above to the bottom of the file 
5)Save the file and close it 

Now when you run the registry fixer it will ignore this key and prevent the need to reinstall Style XP.
