MP4S File Complications

Troubles Opening MP4S Files

Unknown Software Isn't There

Double-clicking your MP4S file prompts the message "%%os%% Can't Open MP4S File". Customarily, this means that Unknown Software is not installed on %%os%%. This will prevent you from double-clicking to open the MP4S file because the OS doesn’t know how to handle it.

Tip: If you know of another program that can open your MP4S file, you can try opening it by selecting the application from the programs listed.

Outdated Unknown Software

In some cases, you might have a newer (or older) version of a Unknown File Type file that is unsupported by your installed application version. If you do not have the proper version Unknown Software (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. Most of the time your Unknown File Type file was created by a newer Unknown Software than what you have installed.

Tip: If you right-click on your MP4S file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Primarily, problems experienced when opening MP4S files are due to having the incorrect version of Unknown Software installed on your computer.
