Did you encounter errors during installation? The tablet resides at the deepest part of the file tree, so it's usually what's affected by the long path issue. When the tablet fails to work, do all the other avionics work?

Hi,
Yes I did, from the first installation I had this error (see picture for my error during installation).
Then with a second install the installation continued, was able to load the plane but the engine page on the tablet was missing.

Uninstalled again, then the solution came from Derek (JF Staff) :

I followed his solution and the plane was loading fine, except that the tablet is sometimes black and sometimes not.

I took a flight today after having to reload the plane a few times until my tablet was working. When the tablet was active, I did not have the impression during my flight that anything was wrong with the plane.

Installing the setup file at the default location, which I normally do for all Black Square planes, wouldn't work for the Commander 114.
However, when the tablet was black, I didn't perform a flight, so I have no idea if the plane would work properly with a black tablet.

So currently, something is probably still not right.
Kind reagrds.
