Are you looking in the right place? The Style Dials are at the very end of the list of Pro Channel plug-ins that you access by right-clicking on an empty space in the Pro Channel. I can access them in Manchester, but when they first appeared, it took me a while before I figured out where to find them.

Are you looking in the right place? The Style Dials are at the very end of the list of Pro Channel plug-ins that you access by right-clicking on an empty space in the Pro Channel.

(I had previously been on Gloucester 21.6.00.25, when I updated to Manchester.)  There are 17 modules listed for insert in ProChannel when there is nothing but the Quad EQ present.  This includes the "not included in the box" stuff like Concrete Limiter, VFX Delay, PC-2A variants etc...but no Style Dials.
 
Note that the ProChannel list doesn't have a scroll bar on the side suggesting that there are other modules that aren't visible in the list.

There is no scroll bar for the PC module selector. If the list does not fit, there are arrows at the top and bottom of the list.

I have a regrettable lack of arrows

Is the VST scanner set to automatic background scan or scan on start up?

Automatic Background Scan
 
I tried just hitting the scan button...but it didn't turn up anything different.  Doing the scan on startup didn't change anything either.  I'm resisting doing a full reset.

I got my style dials back! 
 
The issue was that I'd compressed the files on my hard drive to save space, but have now decompressed, and the style dials work as expected. 

Going back to one of my earlier questions...
 
Where should these be found in the file system?
 
It would be helpful to see if this is just a consequence of a VST scan not running correctly...or whether the dll's responsible for the Style Dials appearance are just plain missing.

Your description of the contents of "...Shared Utilities\Internal" folder seems correct albeit in an unusual location. The default for the PC files is "C:\Program Files\Cakewalk\Shared Utilities\Internal."

Hmm...
 
The folder discrepancy doesn't surprise me...as it reflects a decision I made (many) years ago to keep all of my music related applications under C:\Music rather than the massive unrelated heap that is C:\Program Files...which became C:\Program Files and C:\Program Files (x86) when 64 bit executables came along.  That decision has led to an unsupportable level of added complexity in recent years.
 
With that in mind though, I had already looked in...
 
C:\Program Files\Cakewalk\ and C:\Program Files (x86)\Cakewalk\
 
For a Shared Utilities directory and found none.
 
Let me be a bit more direct then...
 
What dll's, if any, are responsible for the Style Dials?
 
 
(...and please...don't take off on a tangent about the non-standard installation.  That won't be helpful.)
