Cbt new install on windows 7 pro not working

Do you have a look at this thread ?

CBT not working

That one is probably caused by the urbctctl_lock.exe process you probably have running. But that indicates that all the previous setup steps worked and it e.g. fails to load the driver at startup for the volume(s). You could try killing urbctctl_lock.exe and then the install, then reboot… What Windows version are you using?
