Drum Replacer won't appear in Region FX after downloading

[Chevy]

Hi guys,  back after 5 years off...   trying to get Drum Replacer working.  Downloaded fine, seemed to load fine, but doesn't appear in the Region FX dropdown.  Rebooted computer... no dice.  Tried to reload add-ons, but Assistant says it's already loaded.  

Any ideas?

Try doing a VST scan from within Preferences

Does the path to the VST actually exist in Preferences?

Doh!   didn't realize it was a VST.....  that did it, thanks much!
