I'm also having problems with the launcher.exe. My HD is partitioned in two units: C: and D: My C: unit is where I have windows installed, while my D: unit is where I keep most of my files and where I install my games. I started having problems with windows and had to format my C: unit. After I reinstalled windows, all my games were still there in D:, but the launcher for W2EE stopped working. I don't even get an error message. Funny enough, if I go to the bin folder and start the game directly through the witcher2.exe, it works! Apparently, something related to the launcher is installed in C:, not D: with the rest of the game files, but I don't know what it is or how to fix it. Can anyone help me with this?
