sheldonh: Hi folks,

[Edited to include Witcher errlog]

I get this on a Windows 7 64bit box:

The Witcher Crash Log
==============================================
Build: [Plus] 1.4.5.1304 (11/04/08 13:51:26)
Exception: EXCEPTION_ACCESS_VIOLATION

This is with an AMD Phenum II X4 965 Processor, 4GB of RAM, 4GB of swap, 2 Radeon HD 5750 cards (with Crossfire enabled or disabled, makes no difference). I'm using ATI's Catalyst 11.5 driver.

It's difficult to Google for this, because most of the hits are at thewitcher.com, either broken or hidden behind a "new web site coming soon" splash page. Still, I dug around the Google Cache and found these 3 possible problems:

* Not enough memory (N/A, because 4GB is enough on 64bit).
* Run in WinXP compat mode (no diff).
* Run in Vista compat mode (no diff).
* Run as administrator (no diff).
* Upgrade video drivers (no diff).
* Disable sound in game options (no diff).
* Reduce graphics options (no diff).

People in this forum report that the game works great for them on Win7, so I have hope.

All ideas welcome.

Thanks,
Sheldon.
