The patch just makes my game crash when launching. Windows 7 Pro 64-bit.
Does it do it when you start a brand new game as well? Once you install the patch, you can't continue any pre-patched games.
I run the game on Win 7 64-bit, no problem. If you're having problems even getting the game to run, try right-clicking on the Arcanum icon, clicking Properties, and typing or pasting the following into the Target window, including the quote marks: "C:\GOG Games\Arcanum\Arcanum.exe" -no3d -scrolldist:0 -scrollfps:70
If that still doesn't work, try running the game in compatibility mode set to an earlier version, such as Vista, or even Win XP.
And if that
doesn't work, it may be a graphics card compatibility issue; which I can't help you with, but others here might be able to. Good luck.
