Hi there ..
Found out that the game works without installing it like an APP...Didn't manage to install the itch.io APP anyway...
My system was fully installed on the Windows 7 Ultimatum that I had before and haves a couple of Month ...Nothing is wrong with my Windows 10 install at all...Never had this problem with any App like this, also have installed Steam, Origin , that work on similar ways and no problems with them of what so ever...
Anyway I downloaded the game..Finally cause it takes an eternity ... and extracted it to the desktop and upon running the game exe the game worked like that !...
So far didn't had any problem with it this way ...Works like a portable Game ...
