MPEG-4 Decoder Uninstallation
Date updated: February 09 2012
How can I uninstall the Elecard MPEG4 decoder?

You can use the regsvr32 program to cancel the registration of any filter.

For Windows:

  • Click "Start" -> "Run";
  • In the "Open" line you should type: regsvr32 /u "C:\Program Files\Common Files\Elecard\*.ax",


  • regsvr32 - the name of the program;
  • /u - the key to cancel registration;
  • *.ax - a name of the filter file. In your case em4vd.ax or mcm4vd.ax;
  • C:\Program Files\Common Files\Elecard - a path (an example), you should find the *.ax file in your computer and write the corresponding path.

Do not forget to put inverted commas like this ( "C:\Program Files\Common Files\Elecard\*.ax" )!

NOTE!!! If you've uninstalled the Elecard MPEG-4 Video Decoder you have to use any other Video Decoder instead to be able to watch MPEG-4 Video.
