Ok, here is what you should do about your 32 bit plugins.
I found this fix by accident.
Find the bitbridge.exe program and not the bitbridge.dll and copy and paste it to your StartUp folder of Windows.
It is the folder that is in User, Yourname, Appdata, Roaming, Microsoft, Windows, Start Menu, Programs, Startup.
For some reason, if X1 has BB.exe in Startup, then it does not make me rescan my 32 bit plugs anymore.
This happens to 3 machines already, since 8.5.
