Troubles Opening MSWMM Files

Microsoft Windows Live Movie Maker Not Present

You encounter an error message such as "%%os%% Can't Open MSWMM Files" when trying to open your MSWMM. If this is the case, it's usually due to the fact that you do not have Microsoft Windows Live Movie Maker for %%os%% installed on your computer. Your operating system cannot associate your MSWMM with Microsoft Windows Live Movie Maker, so double-clicking the file won't work.

Tip: If you don't have Microsoft Windows Live Movie Maker installed, and you know of another program to open your MSWMM file, you can try opening it by selecting from the programs listed under "Show Apps".

Obsolete Version of Microsoft Windows Live Movie Maker

Occasionally, you might have an outdated version of Microsoft Windows Live Movie Maker installed that's incompatible with your Windows Movie Maker Project type. If you've got the wrong version of Microsoft Windows Live Movie Maker installed, you'll need to install the correct version. This issue mainly occurs when your Windows Movie Maker Project file was created by a newer version of Microsoft Windows Live Movie Maker than you have on your PC.

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

Primarily, problems experienced when opening MSWMM files are due to having the incorrect version of Microsoft Windows Live Movie Maker installed on your computer.
