Cubase is more annoying with VST. By default every VST is installed at program files (x86) vst plugins or program filesvst plugins but cubase does not. It's default location is at program "files : steinberg : vst plugins". So what you have to do is to put the default location program files vst plugins at cubase's vst list.

Same as reaper, 32bit vst is in program files (x86) vst plugin. The 64bit vst is in program files steinberg vst.. I think it is possible to pick multiple folders to load vst from.
