Just to clarify, Yes I do know I need to use the launcher, but I was testing whether there are other ways in and gathering as many errors as possible for you guys. Furthermore I don't install any games on my c drive as i keep it primarily for windows...
I have tried the compatibility mode for all the win xp's and lower and none allow me to accept the eula and for ****s 'n giggles I even put on compatibility mode for all the exe's in the game folder...
And before you ask, yes I am admin of my system, yes I have the latest drivers for all my hardware, yes i have tried troubleshooting without the firewalls and anti virus on my pc...
I hope this info in some way help you guys to iron out some bugs for us win 7 people...
EDIT:
Also to test your theory, I have installed the client on a Win Xp pc and had the same problem. Therefore I have to believe that your latest client version is FUBAR...
