Thanks Alex,
 
That makes perfect sense, to store vst away from the Program folder.
 
I may start with Nomad plugs first, since the installation is quite simple - just one concern if Sonar scans 2 similar Nomad plugs one from the Integral Pack, the other from X3 Pro.  
 
Edit : Not an issue, Blue Tube plugs that came with X3 Pro (Studio Mixing Suite) is a subset of the Integral Studio III's Blue Tube. Skipping the X3 Pro Studio Mixing Suite / Blue Tube plugs via custom installation should do.

Yea, I had problems w/ Nomad on a iLok - SONAR must have messed it up w/ their installation.  Got the 64 bit version and had to get a new serial since the old 32 bits were on the ilok.  Nomad was really good to work w/ on this.  64 bit programs now authorized and good to go after I uninstalled the old ones - I guess including SONAr.  That way I didn't have to reinstall SONAR.

Sidenote:
 
I motivated myself to fix the Pentagon permissions issue once and for all and found this workaround (requires changing a registry permission , so comes with a caution as always):

Well I believe the default paths Sonar provide are not convenient. In my view VST's should not be installed inside the PROGRAM FILES folder as this can lead to permissions issues (meaning you always need to run Sonar as Admin). I have moved my plugins elsewhere and have organised then into specific folders. Every time I install or update plugins I always change the default folder paths. The only code I get permissions issues with now is Pentagon, one of these days I'll grant the file itself admin rights.

Now that is very interesting. Cheers.

I don't take credit for getting plugins out of PROGRAM FILES folder BTW, some other forums poster came up with this not so long ago (I wish I could remember who but it was a great idea).

Solution is summarized on the top post.
