Understanding MP21 Issues


Common Problems Opening MP21 Files

Missing AXMEDIS Editor

Double-clicking your MP21 file prompts the message "%%os%% Can't Open MP21 File". Usually, this is because you do not have AXMEDIS Editor for %%os%% installed. This will prevent you from double-clicking to open the MP21 file because the OS doesn’t know how to handle it.


Tip: When another MP21 application is installed, you can choose to open it by selecting "Show Apps" and using that program.


Wrong Version of AXMEDIS Editor is Installed

In other instances, your AXMEDIS MPEG-21 Object file version may not be supported by your version of AXMEDIS Editor. If you do not have the proper version AXMEDIS Editor (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. Your AXMEDIS MPEG-21 Object file was probably created by a newer release of AXMEDIS Editor than what's currently installed your computer.


Tip: You can sometimes get hints about the right program version by right-clicking on the MP21 file, selecting "Properties", and looking at the version information.


Conclusion: The majority of MP21 file opening issues are due to not having the correct AXMEDIS Editor version installed.


Additional MP21 Opening Issues

Even with the correct version of AXMEDIS Editor installed, you can still experience difficulties opening MP21s. If you are continuing to have errors with loading MP21 files, other external issues might be to blame. Other contributing causes:

  • File corruption affecting your MP21 file
  • The MP21 is infected with a virus
