My Flight Simulator is installed on a custom folder. When I try to install, I’m facing this screen:

I tried to run as administrator, without any luck too! Since Beta 22, I’m not able to use Navigraph AIRAC with MSFS.

Hi,  
what sim version do you have? Steam, Marketplace or the CD version. Depending on this answer, we can look onto a special folder on your C drive, where the sim stores some setting files.

The custom community folder is a second step and can be somewhere, like you (or also I) have.

So, which version please that we can go ahead …

Cheers  
Richard

Still facing the same error. No simulators detected.
