Gears Of War PC Error “modified execute code”
Error Message
There are nearly always bugs in games, even if some are smaller than others, I am about to tell you how to fix one of the error messages that you could receive when starting Gears Of War for the pc. And how to fix it easily.
If you receive the error message:
“PhysXCore.dll You cannot run the game with modified execute code.”
Or any other error message with “You cannot run the game with modified execute code“.
Fixing the Error
- Put in your Gears of War DVD or CD
- Go to -> My Computer -> your DVD Drive:\ (labeled gears of war) -> browse to the following folder
- “Drive:\program files\Microsoft Games\Gears of War\Binaries”
- (If you don’t have the disk you can download the files at the bottom of this post)
- Right click copy “PhysXCore.dll“
- Then browse to your Gears of War installation path
- “Installation Drive:\Program Files\Microsoft Games\Gears of War\Binaries”
- Then paste the file in that folder.(PhysXCore.dll)
- Replace the file then close.
Now you should be able to open and run Gears of War as normal.
Their are other variants of this message such as openal32.dll, in which the same process can be used to fix the error. You just need to use the file openal32.dll instead of PhysXCore.dll when following the instructions above.
Required Files to fix:
Download openal32.dll and physxcore.dll here.
Finding Aztec Crysis Trailer i made a while ago. Its my tribute to the first guy that died on crysis that didn’t play much part in the game!
Feeling sorry for Aztec I’ve made him his own remembrance video.
This Little Trailer was created in 3rd person view on crysis 1.

have you tried setting your date to anything before January 31st, 2009 as Snoopy suggested? or maybe copy the g4wlive.exe file from the disk instead?
Good luck.
