How to set XnViewMP as default photo viewer (Win 10)?

[cadu]

Hi,

As showed in a snapshot of my computer running Win 10, XnViewMP 0.79 ins't listed among apps that can be set default photo viewer: http://i.imgur.com/A7qDDKc.png

For instance, FastStone appears in this list. I tried to reinstall XnViewMP 0.79, but it keeps not being listed.

How to set XnViewMP as default photo viewer? Is there any workaround to make it appear in the default photo viewer list?

Thanks,
Cadux

I'm running Windows 10 64bit.
I used XnViewMP 0.79 Setup Win 64bit.
Tried to reinstall XnViewMP, but it is still out of the default photo viewer list.
If you need more info, just let me know.

you need to search XnViewMP>Capabilities, and remove this key, and reinstall it
