A complete miss. Listen to my words, not only read
Obtaining location of exe/dll gives you nothing. Read my previous post once again. You should understand what role a driver plays in the system - notice it operates on kernel level.... You can kill/disable DaemonTools in a proper (professional) way.
"what else can you do to search for those files if changing the registry entries failed?"
Forget this idea - it is too simple and not effective.
Scanning files/directories/registry is not the way. What if I will change file name? What if I will change registry key location? What if I will change registry data?
Think about it.
Good luck.
