Your registry does not show a valid Prepar3d installation location -- 77W expansion

I just upgraded to an M.2 SSD and did a fresh windows install. 

Installed P3d and various add ons including PMDG 747 and PMDG 772. Now, the 77W expansion pack is giving me this error shown in the title.

 

What gives? the 747 and 772 installed and function fine.

The expansion pack is not yet compatible with P3D v4. I assume you are referring to v4?

Full names required in the forums as per the rules. As Peter said, the 77W is still being upgraded foe P3Dv4. There was an issue with P3D itself that meant the taxi cam could not function but this has now been resolved in the latest P3Dv4 hotfix, so the 77W should be available soon.

duh, I already knew this. Sorry, after installing about 30 addons back-to-back I must have forgotten!
