Trouble adding VST instruments into Cubase from different drive

I just recently bought Komplete 12 and am having difficulty getting all of the effects and instruments into Cubase. I have my default drive C, but it only has 250 GB so I could not fit everything onto it. I installed most of the other instruments on Drive E that I have for storage, however when I try to scan that drive in Cubase, it does not find anything. Is it required to have the VSTs on the default C drive?

I have the exact same problem. Except with EW vst plug-ins. Did you ever get any replies? I see you asked this question a year ago.
