The ut3demoxp642k3.zip file you have requested: Official Releases / Patches / WinXP 64 and Windows Server 2003 UT3 Demo Fix - 9.46mb is not available. Perhaps try browsing all files for the game Unreal Tournament 3 and upload any files you want to share or are missing. This is the only information we could locate:
This is 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.
