Troubles Opening AMX Files

Half-Life Isn't There

When you double-click your AMX file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to Half-Life missing in %%os%%. The typical path of opening your AMX with a double-click won't work because %%os%% cannot make the program connection.


Tip: When you have another program installed that you know will open your AMX, you can select it from the other programs listed (see "Show Apps").


Half-Life is Out-of-Date

Your AMX Mod Plugin File file is incompatible with Half-Life because you might have the wrong version installed. You will need to download a newer version of Half-Life if you don't have the right version. This issue mainly occurs when your AMX Mod Plugin File file was created by a newer version of Half-Life than you have on your PC.


Tip: Right-clicking on your AMX, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.


Conclusion: The majority of AMX file opening issues are due to not having the correct Half-Life version installed.


Additional AMX Opening Issues

You can still experience errors opening AMX files even with the latest version of Half-Life installed on your PC. If you're still experiencing problems opening AMX files, there could be other computer problems. Additional factors include:
