3. Now you can close the properties window and wait for the update to download.

4. Navigate to the latest Release on the GModCEFCodecFix Github page.

5. From that page, under Assets, click the appropriate package for your operating system to download the executable.

chmod +x
and drag the file onto the Terminal window, then press Enter.

7. Double click the GModCEFCodecFix file. When the script runs, it will say what it is doing. If the files are not patched yet, the patches will download. Depending on your internet speed, this step can take a moment.

8. When finished, you can launch GMod from the GModCEFCodecFix window by typing "y" and pressing Enter. If you do not wish to run GMod now, type "n" and press Enter.

Note: If you are using Nvidia graphics, you may need to set the following launch option for these instructions to work successfully:
Code:
SDL_VIDEODRIVER=x11 %command%

Congratulations! If you made it this far, you're done. Luckily the executable does pretty much all of the work for us this time.

To avoid the file patches reverting to the files included with GMod, be sure to use the GModCEFCodecFix executable to launch GMod, or launch GMod via your games list. Using most methods of game launching on Steam forces a file validation pass which will revert these patches. You'll have to run the executable again to re-patch the files if you do this.
