openHAB-Designer won't open on Debian Jesse

Hey All!

I’ve extracted the contents of “distribution-1.8.3-designer-linux64bit.zip” to the folder “~/opt/openhab-designer64/”. When I double click the file, a popup appears saying “[the file] is executable. Do you want to execute it?” with options of “Execute”/“Execute in Terminal”/“Cancel”. All these options simply close the window and nothing new occurs. I’m on Debian 8.0 (Jesse). I updated Java. All the

I then tried in terminal:

xdg-open OpenHAB-Designer

and got error:

Can’t call method “get_vaulue” on an undefined value at /usr/bin/mimeopen line 162.
Error: no “view” mailcap rules found for type “application/x-executable”

I also tried regular open without luck.

Any thoughts?
