Copy the name of the file and path in the Start Run box
Lets say regsvr32 C:\Windows\System32\msvcp70.dll This will say Failed to load
regsvr32 C:\Windows\System32\NCTAudioCDGrabber2.dll If it succeeds,. a message will say succeeded
If you have a path with spaces like C:\Program Files,. you need to put quotes on both ends
