I just installed the 2017.07 update.  I have my VST scan set so that I manually have to scan.
 
When I scanned for VSTs after the installation, I got the an error message that said: "The following plugin caused and error during load: Dimension Pro x64.  The failure point was reported as: Main Call
 
I also noted that Dimension Pro was not available in Sonar. 
 
I've tried to uninstall Dimension Pro and Reinstall (V 1.5), "resetting" all my VSTs and rescanning and still receive the same error.
 
Anyone have any ideas as to how I can get Dimension Pro (v1.5) to successfully scan?  Anyone else have this error?
 
Thanks in advance,
Paul
 
PS - At this point, I don't think it's related to the 2017.07 release.  I haven't used Dimension Pro in a project for several months.
 

It should be OK to ignore the error and enable the plug-in. I believe this is caused by memory getting trashed by plug-ins scanned before DPro. I occasionally get this error on plug-ins I know to be good and have never had a problem enabling the plug-ins.
 
If you told the scanner to disable the plug-in you can get DPro back by either:
 
moving the DPro dll out of the scan path
run a scan
put the DPro dll back in the scan path
run a scan
 
or
 
run a manual scan with "rescan failed plug-ins" enabled (make sure to deselect the rescan option after running the manual scan).
 
To read about the scan options in preferences see http://www.cakewalk.com/Documentation?product=SONAR&language=3&help=0x22B07
 

Your theory seems to be correct.  Rescanning all plugins causes D-Pro to get an error.  Rescanning only the failed plugins allowed D-Pro to be successfully scanned.
 
Thanks for your help,
Paul
