I had set the VST scanner to operate manually but now I can't scan manually, have tried to reset it to scan on loading and background and no scan happens. the manual scan button is grayed / dithered out and clicking the button does nothing. I 've not ( don't think) I have changed anything else. Any Ideas?
Running platinum updated, win 10
Any help here greatly appreciated!
Thanks guys!

When the scan buttons are disabled, it means SONAR cannot find VstScan.exe. This could be due to a bad path in the registry entry VSTScanPath  in HKEY_CURRENT_USER\SOFTWARE\Cakewalk Music Software\SONAR\Cakewalk VST X64 (this is the current 64bit SONAR path). Or it could be the VstScan.exe is missing. The default location for the VstScan.exe is C:\Program Files\Cakewalk\Shared Utilities. The VSTScanPath in the registry contains the fully qualified file name. The default entry is C:\Program Files\Cakewalk\Shared Utilities\VstScan.exe.
 
I believe a full personalization of SONAR (CTRL key while opening SONAR) resets the registry entry. Directly editing the registry should work too. Roll back and Update from the Command Center or running the SONAR installer manually should restore the exe.

I'll give it a shot, thanks!!

It worked! Thanks so much once again!!
