Issues Opening MK3D Files

Missing CyberLink PowerDVD

If this is the case, it's usually due to the fact that you do not have CyberLink PowerDVD for - installed on your computer. You won't be able to double-click to open your MK3D because your OS doesn't know what to do with it.

Tip: If you don't have CyberLink PowerDVD installed, and you know of another program to open your MK3D file, you can try opening it by selecting from the programs listed under "Show Apps".

Obsolete Version of CyberLink PowerDVD

In some cases, you might have a newer (or older) version of a Matroska 3D Video File file that is unsupported by your installed application version. Installing the latest version of CyberLink PowerDVD from CyberLink is recommended.

Tip: Right-clicking on your MK3D, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
