[Error] Failing to launch, no RO2 folder in Documents/My Games/

I am having fail to start problems.



I have purchased RO2 on steam. Installed it correctly, by itself, verified the files are fine.



When loading, it quickly goes from "performing first time setup" to "Failed to start game (Unknown Error)", all in steam app windows.



I have manually tried running RO2Redist.exe & PnkBuster.



I have tried recording a log file, but there is no RO2 folder in my documents/my games/ section, and thus no config.ini also.



Tried re-installing.



I am running Windows Vista 64bit

GeForce GTX 280

4GB RAM

Intel Quad CPU Q6600 @ 2.4Ghz



It's 5 years old (was top of the range), but not failed to play a game yet, only recently stuggling to use max settings on some new games the last year. And well its crashing during initial setup from my guess anyway.



At a bit of a dead loss here, any ideas?

Thanks
