If you are running 64-bit, you will need to add a second path to your plug-in scan (the scan will also get subfolders, so you only need the top folder assigned). For a default installation, you will need these two paths:
C:\Program Files\Cakewalk
C:\Program Files (x86)\Cakewalk
64-bit programs (and plug-ins) default to "Program Files" and 32-bit versions will be in "Program Files (x86)"
