------------------------

it seems this may be your problem - what resolution are you playing at / is your system set to?! - if its very high, then I suggest trying out a lower resolution in your system settings and seeing if that works.

Edit: I'd also suggest contacting support: http://www.gog.com/support/contact
though with it being the weekend you wont likely get a reply from them until monday.

resolution set on my pc is 1920x1080. tried to lower it, same result - game crashes

and thanks, i will contact support

No worries and good luck - I'm out of ideas :)

I had the same problem.

Support said I should update Galaxy if I had it installed. I don't use Galaxy so I removed it instead. It still crashed. It turns out the the uninstaller doesn't remove everything from your computer. On Windows 7 lots of stuff hung around in C:\ProgramData\GOG.com. After deleting that Prison Architect worked just fine.

So much for optional client!

(Updating Galaxy also works.)
