X-Plane 11 Demo installation not allowed

Question

I downloaded X-Plane 11 installer for Windows (initially in a separate drive, then as strongly recommended in C:/.../Desktop). When trying to run it there is a message that says: 

X-Plane cannot open graphic interface file

It appears that you have moved X-Plane program out of X-Plane 11 folder

and so on.

Both installations (1st at F:/ drive and 2nd at C:/ drive as default) didn't open.

These are printscreens taken after default installation

Answer 1

Although strongly recommended to install X-Plane in default C:/Users/.../Desktop this is because it's easier to run the program (x-plane11.exe)? I have knowledge about using options for installations and usually I place all my simulation programs in a separate drive.
