Exchange 2013:  NET Framework 4.7 on CU6

Last Modified: 2018-02-26

I was asked for help with an Exchange Server 2013 CU6 on Windows Server 2012 R2 which was behaving in an odd way.  Wanting to patch it, I found out that .NET Framework 4.7.02558 is installed.  (that's what it sais in HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Full)
Trying to install CU18 or CU19 I get first thing:  .NET Framework 4.5 or higher is required to install Exchange Server.

I read this:

The named KB3186539 and KB3186568 are NOT installed (at least I can't find them in the list - it seems to stop at KB37... and then carries on with KB40...   There is only one or two KB38...-Patches in the list.

Don't know what to do now.  Any ideas?
