64-bit support for Cakewalk synths

I tested all the Cakewalk synths in 64-bit Sonar 8.5.3 and found that several are 32-bit only (and use Bit Bridge) and a bunch more don't start at all. 

64-bit:
  - Cyclone
  - Dimension Pro
  - PSYN II
  - Rapture LE
  - Roland GrooveSynth
  - Session Drummer 3
  - SFZ
  - SI-Bass Guitar
  - SI-Drum Kit
  - SI-Electric Piano
  - SI-String Section
  - TruePianos
  - TTS-1
  - z3ta+

32-bit only (uses Bit Bridge):
  - Beatscape
  - Cakewalk Sound System
  - DropZone
  - RXP
  - Square I

Broken ("failed to insert soft synth"):
  - Dimension LE
  - DS864 DXi
  - nPulse
  - Pentagon I
  - VELOCITY

Is this list consistent with what everyone else has noticed?

Are there any workarounds for the Broken synths?  Am I missing much if I cannot get them to work?

Are the broken (32-bit DXi only) plugins generally redundant with the other soft synths?  Am I missing anything by continuing to use 64-bit?  Or should I consider switching to 32-bit in order to try out the broken synths?

In my opinion you won't be missing much. You can install both the 32 and 64 bit versions of Sonar on the same computer so it would not cost much time and effort if you wanted to try them out.
 
Dimension LE  - 100% Redundant as you already have the PRO version working in 64 bit.
DS864 DXi  - I think this is Dreamstation? If so you are not missing much. It was a good synth in its day but with Z3ta, Rapture, Pentagon, Square etc it does not bring much to the party. You will also find quite a few free VSTi that cover similar ground.
nPulse - Not in the X1 producer package. I really don't know much about this one. Its a drum synth apparenty. I must have tried it in an earlier version of Sonar and not been impressed as I had forgotten it even existed.
Pentagon I - It works, it should be a native 64 bit DXi, something is not installed correctly. I have just installed 8.5 64 bit on my new laptop and it worked straight out of the box.
VELOCITY - See my comments on nPulse

Was Pentagon I included in Sonar 8.5?

Yes.
 
 I am wondering if you have an older version installed. I suggest you uninstall it and reinstall from the Sonar 8.5 disk.

I googled, and saw a recommendation to run Sonar as administrator.  When I do this, Pentagon I works.  There doesn't seem to be a workaround to get Pentagon I working in normal user mode.

I only had to do the Run As Administrator the first time and now I just click on it and it runs just fine. 

Maybe. I honestly don't remember, but I found the answer in this forum...but it was a while ago. 

If your Pentagon I works, when you double-click on it in the plugins list, do you see a filename associated with it?  Or is it blank?
