I have a server that is attempting to install the SP1 CU4 update for SCCM 2012 client but never succeeds. If you go into the Software Center on the machine, the status is continually stuck at "Downloading information".
I tried to force it by copying the installation package to the server and running the command line option specified in the package properties (msiexec.exe /p configmgr2012ac-sp1-kb2922875-x64.msp /L*v %TEMP%\configmgr2012ac-sp1-kb2922875-x64.msp.LOG /q REINSTALL=ALL REINSTALLMODE=mous). The installation ran and appears to have been applied successfully (the version of the client shown in Control Panel --> Configuration Manager Properties went from 5.00.7804.1000 to 5.00.7804.1500) and the Software Center icon went away afterwards.
I was just finishing up congratulating myself when I received a notification from the Software Center again that software was being installed. I opened up Software Center, and there it was again - SP1 CU4 stuck at "Downloading information". I've rebooted several times, but Software Center continues to pop up every time with same status.
One thing I should note, I recently migrated my SCCM server to new hardware and this "problem server" was installed after the migration. Prior to that, all of my other servers received the SP1 CU4 without issue. Both servers (SCCM and problem server) are Windows Server 2012 R2.
