I just got this game last night via the Humble Bundle, and it won't start when I run the application. I'm on Windows Vista 32-bit with ATI Mobility Radeon HD 3400 Series as my laptop's graphics card. For the error, it simply says "WorldOfGoo.exe has stopped responding", and puts this into the crash.txt file:

Update your graphic card driver and DirectX. Also, you might want to check your sound card driver. If non of the above work, try running WoG as admin.

(And if you have the Steam version, run it from Steam.)

Running as admin worked (I saw this method earlier today on a different topic), but is there a way to run it as admin through Steam? I didn't purchase it through Steam, but I added the .exe to the games list.

I don't know anything about Windows 7 but do the instructions given here help at all?
