Nope. When you dropped them in there you over wrote files that should not have been overwritten. You are going to have to do a clean install to get things working properly.

Yu can then link your mess combined runtime as an additional one, or better, delete that mess you created, and just add your old runtime as an additional one.

It probably been said here well over 2000 times, never EVER dump a older version runtime into a newer version install.

Way too many people take way too many things way too seriously.
