Since i just got ignored last time here it is again:
bought through steam and when i try to install, an error comes up that says: "you must have at least windows XP service pack 3 installed "
the game then loads normally, until you try to create a game, then UDK.exe stops responding.
Windows Vista Home Premium (32-bit)
Intel Core 2 Quad CPU Q6600 2.40GHz, 2394 Mhz
ATI Radeon HD 3800 Series
4.00 GB RAM
also when i verify cache, it downloads a 6 byte file everytime.
it appears to be this one:
C:\Program Files\Steam\steamapps\common\orion dino beatdown\Binaries\uuuuuUnSetup.Manifests.
