The VST2 plugin can be installed to anywhere you choose, though by default it will install into C:\Program Files\VSTPlugins. Other common places to look are:

C:\Program Files\Common Files\VST2
C:\Program Files\Cakewalk\VSTPlugins
C:\Program Files\Steinberg\VSTPlugins
C:\Program Files\Common Files\Steinberg\VSTPlugins

Most likely Cakewalk isn't looking in the right place - you should be able to add whichever location you installed to from Cakewalk's Preferences under VST Settings.
