Did a quick search for the dll, not in the VST folder.
I'm not sure where the PC dll's reside.
Do you have the CL folder path shown below?
Program Files\Cakewalk\ProChannel Concrete Limiter
the two files are unins000.dat and uninsooo.exe
All the PC modules have the same files in them.
Did you install the x32 or x64 files?
