Fix for UT3 Demo on Windows XP 64-bit and Windows Server 2003
If you are running Windows XP 64-bit or Windows Server 2003 on your computer and you are experiencing problems starting the UT3 Demo--namely, the game complains that "Modified executable code is not allowed"--vogel from Epic Games has just the fix for you:
We created a fix for the game not starting up on Windows XP 64 and Windows Server 2003 systems. This patch has not undergone the same amount of QA as the released demo so I strongly encourage to ONLY replace the UT3Demo.exe with the one from the patch if you are experiencing the "Modified executable code is not allowed" issue at startup.
