didn't work.  it installed plugins and loop content, etc, but it would not install sonar. :(

rename the SONAR Platinum folder (where the SONARPLT.exe is installed), then rerun the installer

sonar isn't installed anywhere right now.  I uninstalled it.
 
however, I tried renaming the Sonar Platinum folder anyway and tried installing again.  no luck.  exact same thing.  

Did you remove the registry entries?

no, I didn't do you know which ones I need to remove or do I just search on "sonar?"

I doubt it is the problem, this feels more like a disk or file system issue. The registry entries are documented here http://www.cakewalk.com/S...n-Install-Instructions

You're right.  It didn't work.

It might be worthwhile trying to update/repair the Microsoft C++ Redistributables to see if those might have something to do with it.

When I encounter strange problems in Windows, my first step (after having checked the Event Viewer for some obvious error messages) is to update all of the Microsoft Visual C++ Redistributables that displays a Change button when being focused in the Control Panel's list of installed programs. Clicking the Change button for each of those files will open a dialogue with an option to Repair. After having run Repair for each of those files, the problem has been fixed surprisingly often.

You may have hit on the problem, but I don't seem to be able to fix it.
 
I have tried to repair some of the MS C++ redistributables and when I click on repair, it pops up a window stating that it's "initializing" but the progress bar never moves. 

That has never happened to me. Can you find any error message in the Event Viewer that relates to your repair attempt?
