VST2Plugins .dll not detected in Wavelab 11

On my new PC Wavelab 11 Elements does not detect the .dll VST2 plugins.
(Windows 10 pro)

Where on my old computer all worked well, same Windows version, same Wavelab version.

Anyone out there who can help??? Thank you ever so much !!!

In Preferences | Plug-ins, is the box checked for the standard locations?

No one, or only some? Where are they located? Are they really 64 bit plugins?
