The reason I recommended a Reset instead of changing the DPro inventory record is we do not know if the DPro record had other errors in it and if the malformed DPro record was a symptom of a bigger issue with the VST Inventory.

I wasn't being critical, scook. I was meaning to be informative.

Respect to you as always.

You gave the right direction.

Understood, I did not take it as a critique and replied to offer insight into why reset may be preferable to manipulating the DPro record.

I had the same problem when upgrading to sonar platinum
i solved it by disintalling D-Pro completely and reinstalling from scratch using the old sonar 8.5 installer...

I had the exact same problem, and "reset all" and rescan was the only solution. How could "select" type solutions possibly work when Dim Pro is simply not there?
This is a brand new Win 10 i7 computer with nothing on it but Sonar Platinum and its plugins, a clean install done by the Control Center without changing any defaults. Everything is registered. Run as administrator is checked. Dim Pro runs as a standalone.
But in Sonar, Dim Pro is absent from every menu, scan, option or preference.
So I added every Dimension Pro and VST folder to the list of scanned paths (this may come back to bite me). My installed plugins jumped from 21 to 170. Dim Pro appeared ...but as a 32 bit audio FX.
When I reset all and rescanned from scratch, the number of installed plugins dropped from 170 to 146, Dim Pro got added as VST instrument and not as an FX. It appears to work, we'll see.

I'm surprised there aren't more reports of this problem in the forum, I guess people don't have angst over removing all their plugins and rescanning.

So I added every Dimension Pro and VST folder to the list of scanned paths (this may come back to bite me).

It is not a good idea to add folders which are already included in the scan path. For example, by default the 64b8it DPro dll is in "C:\Program Files\Cakewalk\Vstplugins\Dimension Pro." By default, SONAR has "C:\Program Files\Cakewalk\Vstplugins" in the scan path. The default causes the scanner to search all the folders under "C:\Program Files\Cakewalk\Vstplugins" including "C:\Program Files\Cakewalk\Vstplugins\Dimension Pro." In the past adding redundant paths to the scanner caused problems.
 
It is also a really bad idea to add folders that do not normally contain VST dlls to the scan path. This can cause the scanner to open dlls which are not VST resulting the scanner hanging or crashing.
 
VST reset or one of the selective scan options above the reset button in preferences are the safest ways to correct scan problems. It is possible to perform surgical fixes with a combination of temporarily relocating VST dlls out of the scan path and removing partial entries in the VST Inventory in the registry. Manipulating the registry is not difficult but is not recommended for all.

Thanks, Scook, for the advice.  Could you or anyone kindly remind me which folders were the default VST folders for Sonar Platinum?  I've gotten the ones I've added all mixed in, "Reset all" left them untouched, and now I'm afraid to delete any of them :-*)

In Preferences > File > VST Settings (where you should be maintaining the path) the defaults are:
C:\Program Files\Cakewalk\Vstplugins
C:\Program Files\Common Files\VST3

Thank you!!

Cool sorted mine with a reset to Cheers
