If you're looking for a solution, this is not the place, I'm just posting some facts. I bought WWP because it had a Vista Compatible sticker but it should said in Vista Copatible in some cases. I couldn't run it in one of my computer (dell inspiron 1420, Intel, Vista Home Premium) with any tweaks, treats posted in the forum. But in the other computer (Acer Aspire 5050, AMD, Vista Home Basic) I didn't have to do any tweaks, I just installed and started playing. It has some crashes though.

I Hope Team17 launches some new service pack or something... :-/

When does it crash, how does it crash (actually lock up PC, return to desktop, error message...), and what is your GPU (Graphics card/chipset)?

Well, for the record, I have a very similar laptop as the guy above (think I posted the spec in the Armageddon thread) and when I start my patched copy of WWP I get a "WWP has stopped working" error :(

did you also update the game?
