Hi,
For testing purposes I'm setting up an Exchange 2013 environment and now I'm trying to install CU 8 (also for testing purposes) but it's not working. When I just start the executable, I get the following error:
"The upgrade patch cannot be installed by the windows installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch."
When I unpack the installer and try to run setup via an elevated command prompt, using:
Setup /m:upgrade /IAcceptExchangeServerLicenseTerms
I get the following error:
"Exchange Server 2013 requires .NET Framework 4.5 or later. Download it from..."
While this Framework is already installed.
I'm currently having Exchange 2013 SP 1 version 15.0.847.32
Thanks already for the help!
