Cannot install PMDG 777

I have P3D installed and have flown default aircraft, but when I go to install PMDG777, I get the message that there is not a registry entry for P3D.  Help!

This is usually because you are using an incompatible version of P3D, or you are using a tool like the Estonia Migration Tool, which messes with your registry.

Well, I don't think it was either of those.  I finally got it installed by removing P3D, changing the drive letter on the P3D drive, reformatting and reinstalling.  Everything seems to be all right now although I did have to go through the simconnect process...never had to do that on my previous computer with Windows 10 64.  

Thanks.
