Confusion over 64-bit dll locations

I am currently rebuilding my DAW to Win7 64-bit with Sonar PE 8.2.2
 
The base configuration, inlcluding all the new 64-bit drivers for audio interface and MIDI controllers is working sweetly.
 
However, when it comes to loading the 64-bit versions of Kontakt 4 (from DVD) and Superior Drummer (V2.2.2 update from download from Toontrack) the dll's for both seem to end up in the directory Progam Files (x86)/Cakewalk/Vstplugins which as I know is a directory for 32-bit apps.
 
Even though at installation I select the 64-bit install, I still get this result. In the case of Kontakt 4, my Sonar VST scan will find it and load it, I suspect I am running a 32-bit version under Bitbridge, but not sure how to verify this. In the case of Superior Drummer 2, again, it will load into a project but not work (no sound). On a second attempt, I did point the install into what I believe to be the correct directory C:Program Files/Cakewalk/Vstplugins but the dll just dropped in without creating a Toontrack subdirectory like it did in the 32-bit directory and although scanned by Sonar it still was the 32-bit non working version.
From searching the forums, I know the 32-bit version of SD2 will not work in Sonar 64-bit and I know its only the 32bit version loading as the 64-bit version reveals itself as so on the SD2 GUI.
 
So, I am going round in circles a bit here and looking for any clues or help from anyone who has been through the successful 64-bit installation of Kontakt 4 and Superior Drummer 2 64-bit.
 
Thanks 

Yes I agree with you Mark, I did complete my DAW rebuild successfully. However the seemingly random placings of DLL's made it a lot more ungainly than it needed to be. I understand that each plug-in vendor will currently structure their installer in a way that works for different DAW's on different OS, but if there was some sort of standard it would encourage folk to upgrade more often, and almost certainly enhance the market for additional plug-in's. I for one keep my plug-in choices to an absolute minimum, one of the reasons being the unwieldly directory structures that end up having to be maintained and navigated just to be able to get musically creative

I had this same problem. This is what I did to resolve it:
1. I created a new folder under Program Files> Cakewalk called "Plug-In Menus" then
    copied my old plug-in menu to this folder.
2. Under Option> Global, I selected "Folders" and pointed the plug-ins to the new folder.
3. Next while still in the Global edit screen I went to VST Plug-Ins and selected "reset VST Plug-Ins" then "re-scan VST Plug-Ins"

Try that and see if that helps!!!
