Windows 7: How do I always open MKV (with double-clicking) files with KMPlayer?

How do I always open MKV (with double-clicking) files with KMPlayer?

I can't make Windows explorer open MKV files with my default media player.

I tried modifying KMPlayer's settings to associate MKV files with it, but had no effect.

I tried,
- Right clicking a MKV file in an explorer window
- Choosing "Open with > Select default program" from the context menu
- In the opened "Open With" dialog box, browse to find kmplayer.exe, then select it
- Click OK to return the dialog box
- (At this step, I don't see kmplayer.exe is listed in the "Open With" dialog box)
- Click OK to exit the "Open With" dialog box
- To see that my media file is still opening with Windows Media Player

Why doesn't windows associate MKV files with my selected EXE file?
How do I fix this situation?

I don't know that player, so I can't answer your question directly, but I have no problems opening or playing MKVs with VLC.

Have you tried this..

Change which programs Windows uses by default

I know it was written for vista, but it's pretty much the same for windows 7.

As an alternative course of action, eliminate WindowsMediaPlayer as an option for Windows to turn to. In the subsection (control panel/programs and features//media features) where one can turn Windows features on/off, turn WMP off and see which program the OperatingSystem will default to. Otherwise, it may be a permissions issue.

Shift-Right Click on a MKV file an select Open with

make sure the Always use this program.... option is selected

if your program is listed select the program.
If not shown expand the Other Programs .... option and select from there.
If still not available you can use the Browse... option to point to the programs EXE file

The file should open and play - and a double click on any other MKV should now open with the program selected

For future reference when you install new players they always ask what filetypes you want it in charge of.
Most people just click next. I suggest looking at the list in the future.
