Hi!
Just tried to install Metric Halo Thump (its free - so i tried).
Switched to Windows Layer - installed from the USB Drive.
Went to C: Drive and searched for the path where it was installed to (think it was something like PlugIns - Audio - MHThump) - did copy the folder to D-drive - PlugIns - restarted Venue - was going to the PlugIn Page and found it under "previous installs" - installed it - and it worked!
The only thing - the GUI is a little BIG!
Just for ur info - maybe together we can try a couple of PlugIns and get an list what works and what not...
