Yeah, it is a tiny installer. Run a VST reset.

 

You know, I wondered about that, but it's a PC module. Would a VST reset have an effect on that?
I'll try it and let you know what happens.
Thanks.

Yes, PC modules are modified VST2 plug-ins. The path to them is silently added to the scanner from an entry in the registry. If you have not run a scan since the update, this is the problem, no need to reset, run a scan. However, if a scan has been run, it may take a reset to pick it up.

WooHoo!!! There it is. You rock, Steve!

Good news.
Which was it, auto scanning turned off or reset required?
Either way, please edit the initial post and add [Solved] to the subject line.
Thanks

I did do a reset, which may not have been needed. I ran a new scan immediately afterward, and Boz appeared in the PC module list.
I do have auto-scanning turned off (out of habit from previous versions) but I understand that is not really necessary any more.
 

OK, the reset was probably not necessary. I use the default setting "Automatic Background Scan." It introduces about 2 second delay when starting SONAR for the initial scan of the folders holding my 700+ plug-ins. Still much faster than older scanners and eliminates issues like what you just experienced.

Copy that. I'll turn on auto-scan for March.
Yeah the old scan was excruciating, so I only ran it when I added new plug-ins.
