What is the proper way to install the EMU Proteus Pack after 32Bit and 64Bit D-Pro?

Hello:
 
I just bought Sonar X3 a week ago or so, and installed both 32 bit and 64 bit variants as a matter of best-practice.  I do this with Cubase too (my primary DAW) and his sister Nuendo too. I mostly only use 64 bit unless there is a very old 32 bit VST that is still needed.  In that case, I start up the 32 bit DAW, record the 32 bit VST part to a metronome or basic drum track, then freeze/bounce/print the 32 bit part it to a WAV for import later into the 64 bit DAW.
 
I see that D-Pro 1.5 comes in 32 and 64 bit flavors, so I want to install both, but I want to ensure that 32 bit VST (the DLL I mean) can only be seen by Sonar 32 bit, Cubase 32 bit, and Nuendo 32 bit and not by Sonar 64 bit, Cubase 64 bit, or Nuendo 64 bit.
 
Typically I use the trick of naming my Vstplugins folders differently so that the DLLs don't get confused between a 32 bit DAW and its 64 bit counterpart.  For example,
 
D:VST Library\Vstplugins\
D:VST Library\Vstplugins 64 bit\
 
Or some flavor of that.  This way where a VST has both 32 bit and 64 bit DLLs, I don't have to waste time futzing around trying to figure out why 32 bit DAW won't even register a plugin (that I later find out is a 64 bit plugin).  JBridge is good of course, but it's always better to run native if you can.
 
Question:  Is this a good strategy with Dimension Pro 1.5 and does it cause Sonar X3 any hiccups?
 
Question 2:  Are there any known issues with installing the EMU Proteus pack (6 disc installers from years ago) after installing D-Pro 1.5 and the so-called "1-3 Expansion Pack" that comes with Sonar X3 Producer?
 
Thanks in advance!

Okay, thanks.
 
I've un-hidden ProgramData.  I'll bear in mind the umm, shotgun blast that the installer might make, and will locate/move whatever to wherever it should be, then I'll test everything.
 
Thanks again!

In most cases registry changes can be avoided and files relocated using the DOS mklink command with the /d or /j switches. For example:
 
mklink /j c:\Program Files\Cakewalk\Dimension Pro\Multisamples d:\DimPro\Multisamples
 
will create a pointer in the default multisample location to the physical location on another drive. This also takes care of old installers too.
