Update 21208 of Acrobat Reader breaks the app, it won’t start on Windows 7.

It shows “This program couldn’t launch because the object api-ms-win-core-winrt-l1-1-0.dll is missing” or something along those lines.

...Please fix.

    Same problem - I cannot open Acrobat Reader on Windows 7 SP1 64bit.

    It was working fine 24hrs ago, and I have not manually changed or updated anything on the machine since then.
