Hi,
I tried to install and launch the 0.4.7.exe.. it worked for me.
When, the game is installed, you have to click on the shortcut on desktop (if you have it) or click on "C:\Program Files\GeoStrategic\GeoStrategic.exe".
The game should appear on full screen.
I also published the 0.5.0 which is better. If you want to try again, better use the latest one.
I will also do others tests on other computers and publish a streaming on my install.
I don't know why it is not working for you... :'( But I am keeping working on a solution. I need to sleep and I will continue tomorrow !
