GMX File Complications

Common Problems Opening GMX Files

GameMaker Studio Removed

When trying to open your GMX file, you get the error "Can't Open GMX File Type". If this is the case, it's usually due to the fact that you do not have GameMaker Studio for %%os%% installed on your computer. The OS won't know what to do with your GMX file, so double-clicking to load the file doesn't work.

Tip: If you have another software that you know opens GMX files, you can select it by hitting the "Show Apps" button.

GameMaker Studio is Out-of-Date

Your GameMaker File file is incompatible with GameMaker Studio because you might have the wrong version installed. Download the latest GameMaker Studio version from the YoYo Games website to ensure you have the correct one installed. This problem is predominately due to having a GameMaker File file version that was created by a newer version of GameMaker Studio than what you have installed on your PC.

Tip: Sometimes you can get a clue about the version of GMX file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Summary: Not having the right GameMaker Studio version on your computer can cause problems opening GMX files.
