Q: Game crashing or other issues on systems running Windows Vista/7
Tip0: Be sure to install the game as Administrator: right click on SETUP.EXE from the DVD and choose Run as Administrator, also do the same for TWEE_upgrade.exe and for TheWitcherPatch.1.5.exe too
Tip1: Be sure your Windows Vista/7 is up to date: "The Witcher may exhaust virtual address space when running on 32-bit Windows Vista. Microsoft has released a hotfix that addresses this problem. Please download the hotfix from the following location when playing the game on 32-bit Windows Vista:
http://support.microsoft.com/kb/940105 . If you have patched your installation of Vista to SP1 or have Windows 7, then you already have this hotfix. KB940105 is already included in Windows Vista Service Pack 1:
http://www.microsoft.com/downloads/...2a-9c9b-4579-b64a-09146a0ba746&DisplayLang=en " ( 64-bit Vista and all Windows 7 versions do not have this problem )
Tip2: On nVidia hardware and VIsta Ultimate be sure to uninstall the DreamScene application as the it conflicts with the video driver ( read the Release Notes of the video driver )
Tip3: Get TweakUAC and set UAC to QUIET, not Disabled ( do run the application again if you want to restore you previous UAC mode )
Tip4: Set the game to run in Compatibility Mode: right-click on witcher.exe -> properties -> Compatibility -> Windows XP SP2 , also check the 640x480 mode, and the disable decorations, then press Apply and OK
Tip5: Run the game as Admin: right click on witcher.exe and RUN AS Administrator
Tip6: If running the game from an external USB drive be sure to set up the currently used Power Settings Profile so that USB devices are NEVER put to sleep/suspend ( the Performance profile is recommended when gaming anyway)
