Cannot install minimwatch on Linux x86-64 machine

[Budgie]

Hi,
Am in over my head here. Minimserver running well on Qnap TS 209 Pro II and being seen by BubbleDS and Kinsky and working as it should.

My problem started with trying to sort out multiple genres on one file. I tried the // separator (delimiter?) mentioned in another thread but the old comma separated genres from Twonky days are still there. At this point with Twonky I would have gone to web interface and forced a database rebuild. I read up a bit more on minimserver and decided I needed to install minimwatch on my linux desktop machine so I could control minimserver but when I tried the installation it crashed with the following:-

Looks like I need something else installed but as I said, in over my head. So two questions:-
Am I going about this the right way?
How do I get minimwatch installed?

After posting the above I tried on 32 bit openSUSE laptop with jre installed. The minim icon appeared OK but seems more blue than any other colour and right clicking gives commands but all controls greyed out. Went to QNAP admin and stopped enabled Minimserver and that seems to be working so help still requested please.

Grateful for help/advice when somebody has time.
