Well, you probably have to start over, uninstall the game, remove the game folder and then reinstall NOT into the Program Files folder... the most likely reason for why the game doesn't start is that one of the configuration files is not entirly correct... and the reinstall should correct that.Anyway, I have a problem running IWD2 on my system, My problem is that my system, for some reason will not play the game at all, as in when I click the Icon, my system never seems to get around to launching it. Not even a process is started.
When you have done the reinstall from the CD/DVD, start the game without any mods in it upto the point it autosaves, then if the game doesn't already have the v2.01 patch, use that from here for example. Then restart the game... then install mods you wish.
The game should also give you a reason why it doesn't start...
I tried reinstalling, and patching. And I'm still getting nothing, not even an error message. Thank you for the reply though, do you have any more suggestions?
