OK. You could try running it with native JRE and mono, but if you do, be
prepared for quite a lot of faffing round. The simple approach of
installing the Windows JRE and .net in the same prefix may be a lot
simpler. I'd suggest you try that first and only look at using the
native JRE and mono if it doesn't work.

The main issue with that sort of mixing is most likely to be the search
paths. Don't forget that, apart from the Z drive, each prefix is set up
to imitate a complete Windows filing system and that each prefix has its
own C: drive, which maps onto $WINEPREFIX/drive_c I may be wrong about
this, but the only way the app running in a prefix is meant to talk to
programs in other prefixes or to native applications is via sockets.
As for the other drives, all defined in $WINEPREFIX/dosdevices, Z: maps
onto /, so is potentially quite dangerous while in my system A: maps
onto a floppy drive, D: and E: map onto my optical drives and K: maps
onto a removable (USB) hard drive.

If you saw my later posts you'll know that I have no need to run more
than one Wine app at a time. Unless I'm using a set of apps that came
from the same source and are designed to work together, I put them in
separate prefixes because that avoids potential problems with
However, I started up two unrelated programs installed in separate
prefixes and both ran just fine without interfering with each other.
They are graphical programs and played nicely with each other when it
came to sharing the mouse. Neither use the keyboard so I didn't tesyt

Glad we were able to help.
