Did Win10 creators update just get rid of some important runtime DLLs?

I have an old-ish application which worked fine on Win10 64-bit.
That is, until I agreed to upgrade to the Creators edition two weeks ago.
Now it simply won't work.
Its complaining of a missing runtime DLL.

Did Win10 creators ed., just get rid of a bunch of legacy DLLs, ... what could a solution be?

Have you tried reinstalling that application ? Did you look for that DLL file and if it actually exists ?
Many programs/applications/drivers use "Shared DLLs" shared with system DLLs and get replaced by some updates to ensure system stability but may interfere with older programs.

tried the reinstall.

They call it "Creator's Update", but I think it should be named "Destroyer's Downgrade".
It's a mess for this OP, and for countless others. Madness.

This is just another example of Microsoft's poor software QA and disregard for its customers.
