Help- Win10 Creators update broke some VSTs, including MOTU.?

Just after I upgraded to Win10 Creators edition, I noticed a handful of VSTs not working. Notably MOTU Ethno & Symphonic, which had worked OK under regular Win10 64-bit.
I eventually got MOTU working as a standalone by (re)installing some runtime DLLs related to Visual C++. Perhaps Win10 creator knocks some DLLs out...?
Anyway, does anyone know what other tweaks to Win10 Creator that'll give me a good chance of getting my VSTs to work again.
(Tried MOTU tech support, - not helpful so far.)
