Congratulations, you're done! 🎉
Tip: To make sure you remain patched and up to date, we recommend launching Garry's Mod through GModCEFCodecFix each time.
It is typically also safe to launch it from your Steam Library after it's been patched, however other ways of launching it may force Steam to perform a file integrity check.
If a file integrity check happens, or GMod gets an update, the patches may be removed and you will have to run the tool again to restore them.
