Not me. Still haven't had any luck, and the only other solution I"ve seen is to remove everything Steam related, uninstall Steam, then reinstall from scratch using Admin mode. I *really* don't want to spend a week re-downloading everything. Bad enough I've now spent three days downloading Witcher 2 over and over again.
I try running 'witcher 2.exe' from that directory, and same thing - immediate return to desktop. Only thing that does anything is 'configurator.exe' (I think that's the name) that tells me my install isn't correct. I also don't have a file called 'paul.dll', which I've seen mentioned in a lot of threads about the game.
