I deleted every Prepar3d file I could find and tried a total reinstall again.  It still came as already installed and on the C drive.

That is it for me.  If Lockheed comes up with an updated version that works, I might try again.

You've probably got entries in your Windows registry that are causing this issue. If you made a system restore point prior to installing P3d, you could use the OS feature to roll back to a date prior to the install. If nothing else was installed after P3d was installed, then nothing else will be affected by the rollback.
