I am considering upgrading from BB 2009.
It looks like I pretty much have to order the USB version for the Ultra Plus pak, I guess PG is not recommending 20 dvds.

But I have so many USB devices hooked to my computer I would rather run Biab using my current setup.
BIAB program files on the C drive and my real tracks on a second drive (external sata with plenty of room).

Can I install from the USB drive into my current setup ?
Thanks
John.
