Tried to follow your procedure for allowing add ons in P3Dv6. Made it to the point where you create a reg entry in Computer\HKEY_CURRENT_USER\SOFTWARE\Lockheed Martin but I couldn't get past the Error Renaming Warning that popped up in your video briefly while trying to create the Prepqr3D v4 entry.
Would appreciate more specifics on how to get past that,
