SCCM 2012 R2 client fails to install Windows 10 Build 10049 or newer

When testing the latest Build of Windows 10 I got an error installing the Configuration Manager 2012 R2 client, it fails installing the Windows Update agent with the following error in the CCMSetup.log file.

“File ‘C:\WINDOWS\ccmsetup\WindowsUpdateAgent30-x64.exe’ returned failure exit code 775. Fail the installation.”

I assume a solution to this error will presented soon, but I cannot wait to get started with my testing of 10049 so installing the SCCM Client with the following command line solves at least the installation error of the Configuration Manager client.

“ccmsetup.exe  /skipprereq:windowsupdateagent30-x64.exe”

Then ccmsetup.exe will skip the installation of the Windows Update Agent and continue the installation anyway. Normally I use the /Skipprereq: command to skip the installation of Silverlight on servers as I don’t want Silverlight installed on my servers. But the command line works great in this case as well.

You will then see this in the ccmsetup.log file on the client which shows that the installation of the Windows Update agent was skipped and that the installation continues.

“Item ‘x64/WindowsUpdateAgent30-x64.exe’ is excluded by the ‘/skipprereq:’ switch. Ignore it.”

God Luck with the testing of Windows 1o!

Update: SCCM 2012 SP2 and SCCM 2012 R2 Sp1 solves the problem so to solve the issue and get OSD working an upgrade is needed. If you just want the client to work and cannot upgrade now, the workaround is valid for newer releases of Windows 10 as well.
