Not seeing X-Plane 12 installation

[WagnerTenor]

Dumb question.  When I open the installer, I see X-plane 11 install button, but not the X-Plane 12 install button.

Any thoughts?

Thanks

Hello Graham,

Do you have X-Plane 12 installed?

The TDS GPS Manager is looking for tthe x-plane_install_12.txt file located here:
C:\Users\%username%\AppData\Local

where %username% is your username

Most likely that file is missing, or the path inside it is incorrect. Resolving the file presence and the correct X Plane 12 path inside the file will get X-Plane 12 to show up in the TDS GPS Manager.
