I have a problem while installing the game, the installbar moves only a bit and than i get that Errormessage:

An Error occurred while trying to rename a file in the destination directory:
C:\Program Files (x86)\GOG.com\NOX\Game.exe

MoveFile failed; code 2.
Das System kann die angegebende Datei nicht finden.

I redownloaded the exe and choose a different directory.

Turn off your antyvirus during installation.

Its now working. thank you very much.
