I figured it out. I just posted this in my thread up stairs but it was a team effort between this thread and that one to educate ole Beepster so I'm gonna paster my solution and thanks here as well... seriously thanks guys:
Holy bleeping jebus poop crackers! It turns out I had NOT solved the problem and spent the past hour trying to figure it out. It turns out BFD Eco just throws itself willy nilly all over the darned C drive... AND there is an issue where unless you have the latest update from august it sometimes won't show up in the host at all even if you do manage to find all the files.
So first I reinstalled BFD. Then I made sure I had the latest update (Version 1.5.1.5) from my FXpansion account. As I installed that update I wrote down every one of the install paths. Here they are... tell me if this makes ANY kind of sense...
VST Plugin Path (32 Bit) = C:\Program Files(x86)\VSTPlugins
App Path (32 Bit) = C:\Program Files(x86)\FXpansion\BFD Eco
VST Path (64 Bit) = C:\Program Files\Common Files\Steinberg\VST2
App Path (64 Bit) = C:\Program Files\FXpansion\BFD Eco
It's in completely different folders! So I added all those to the Sonar VST scan thingy, checked off the ReScan options and let it do its thing. I figure this HAS to work. Well I didn't see anything implying BFD 64 bit in my browser BUT there was a new option that simply said BFD Eco. I inserted that into the track view and clicked the little question mark options button in the BFD GUI, went to the About option and SUCCESS! It was telling me that it was the 64 bit version.
I'm pretty mad I wasted my afternoon screwing around with this but at least I know FAR more about how to use the VST scanner (of which I knew NOTHING before today) and I can use BFD 64 bit. What I DON'T get is why I could see it in X1 after a relatively easy install but it turned into this enormous screw around in X2. Obviously this isn't a Sonar issue but the help menu entry on the scanner was no help at all. You wouldn't be able to understand it unless you already knew how to use it. It IS however a really bad default installation which is on FXpansion. We're not all computer geniuses yanno?
Anyway... my anger and frustration is subsiding now and I'm glad it worked out in the end. You guys, as usual, totally saved my sorry arse and I thank you profusely. Cheers.
