I'm installing Exchange 2010 on a Windows 2008 R2 VM and I get errors on the installation of Client Access Role Prerequisites: The computer requires the update 979744 and 979917. However, when I run the 979744 and 979917 updates I get: the update does not apply to your system.
I can't install Exchange without these two updates and I can't install the updates because Windows 2008 R2 doesn't need them. I have reinstalled a new VM and I still get the same error.
