I changed the permission in Regedit and it worked now. Reset permission afterwards.
I have a remnant of driver for a tv-tuner card and can't remove it. From regedit: %SystemPath%\system32\drivers\PhilMAS64.sys and regedit won't allow me to remove it. I'm the administrator and have permission. Tried CCleaner with no success.
Any suggestions on how to remove it as it is keeping me from installing another tv-tuner.
