Server 2012 R2: Cannot Install .Net Framework 4.7.2 or 4.7.1 .Net Framework for exchange upgrade from cu 19 to 23

Question

OS: Windows Server 2012 R2 with exchange 2013 cu 19

I can't install .NET Framework 4.7.2, or any Windows updates for .NET Framework for upgrading my Exchange server 2013

I tried with Dism to repair store but any time receive store is ok, I receive this error when I run 4.7.2 package.

When running both the .NET Framework 4.7.1 and 4.7.2 offline installers, I get

Exe (S:\55be9ef7754b77f6655f22b680bb\x64-Windows8.1-KB4054566-x64.cab) failed with 0x3712 - The component store has been corrupted. .
Exe Log File: CBS.log
PerformOperation on exe returned exit code 14098 (translates to HRESULT = 0x3712)
Action complete
Error 0x3712 is mapped to Custom Error:
OnFailureBehavior for this item is to Rollback.

Action complete
Action complete
Final Result: Installation failed with error code: (0x00003712), "The component store has been corrupted. " (Elapsed time: 0 00:02:37).

Can someone please tell me something?

Thanks!

Answer 2

OOp also, I remember from past installs that sometimes it is necessary to uninstall or downgrade modern versions of .Net. In this case however, Cu19 requires .Net 4.8. Try installing 4.8, then CU 23

Answer 3

Hi
I treid with 4.8. the same error.
Cu19 requires .net 4.62 or 4.71.
I would update to 23 for hafnium patch
thank u
