Sources of AX Problems

Typical AX Opening Challenges

Microsoft Windows Media Player Removed

If you attempt to load your AX file, you experience a message such as "Can't Open AX Files". Generally, this is experienced in %%os%% because Microsoft Windows Media Player isn't installed on your PC. You won't be able to double-click to open your AX because your OS doesn't know what to do with it.

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

Microsoft Windows Media Player is Out-of-Date

Your DirectShow Filter file is incompatible with Microsoft Windows Media Player because you might have the wrong version installed. If you've got the wrong version of Microsoft Windows Media Player installed, you'll need to install the correct version. Most of the time your DirectShow Filter file was created by a newer Microsoft Windows Media Player than what you have installed.

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

Conclusion: The majority of AX file opening issues are due to not having the correct Microsoft Windows Media Player version installed.
