Tried to launch Inquisitor by double clicking icon. First screen showed "auto config, please wait" followed almost immediately by a screen full of small color bars, mostly green. Then the blue screen of death. Tried several times after uninstall/reinstall, updated drivers,resolution change, etc. My system is XP with NVIDIA GeForce 6200, 4MB RAM

Maybe it's a problem of the game's default resolution/refresh rate. Go to:

C:\Program Files\GOG.com\Inquisitor\GameData and open d3dparams.ini.

Then you can edit "InitialScreenWidth", "InitialScreenHeight" and "MaxRefreshRate".

Since Inquisitor supports various resolutions/refresh rates, you can change these items to your current desktop resolution/refresh rate.
