Sources of MP41 Problems

Common Problems Opening MP41 Files

VLC Media Player Removed

You encounter an error message such as "%%os%% Can't Open MP41 Files" when trying to open your MP41. Usually, this is because you do not have VLC Media Player for %%os%% installed. The OS won't know what to do with your MP41 file, so double-clicking to load the file doesn't work.

Tip: If you know of another program that can open your MP41 file, you can try opening it by selecting the application from the programs listed.

Outdated VLC Media Player

It is possible that your version of VLC Media Player isn't able to open your Microsoft MP41 Video Data file due to incompatibility. Download the latest VLC Media Player version from the VideoLAN website to ensure you have the correct one installed. Your Microsoft MP41 Video Data file was probably created by a newer release of VLC Media Player than what's currently installed your computer.

Tip: Sometimes you can get a clue about the version of MP41 file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Summary: Not having the right VLC Media Player version on your computer can cause problems opening MP41 files.
