X-Plane 11 demo fails to install because it is "unable to read from a .zip file"

Question

I am wanting to try the X-Plane demo before paying money for the full game. I have tried several times to install the demo with no luck because of this error. If I continue the install and load the demo, it won't start because of some kind of .zip error. The text again says "Unable to read from a .zip file (short-read error). It may be missing or damaged." Any help is appreciated!

Answer 1

Extract the .zip file into the folder you have your install program.

I've got the same problem. But I can't extract the zipfile to the install folder, cause the zipfile is where the installer is!
The zipfile contains the xplane 11  installation file for Windows

Move the zipfile out of the install folder to any suitable desktop folder and extract it in that folder. Then move the extracted file back into the install folder.
