--- Comment #6 from Bruno Jesus 00cpxxx@gmail.com 2012-01-22 17:33:38 CST --- What I mean is that the path not found error is not only related to c:\windows\system32\config\software but also to c:\windows\repair\software (which is a backup).
If you have only one of them the program will say path not found, as stated in your first comment.
