I am trying to install System Center Endpoind Protection 2012 Client 4.7.205.0 (KB3036437) and it will not install on two Windows 2003 Servers. It is giving me the following error:
Installation Failure: Windows failed to install the following update with error 0x80070643: Update for System Center Endpoint Protection 2012 Client - 4.7.205.0 (KB3036437).
I completely removed System Center Endpoint protection and reinstalled. When I first installed SCEP it was version 4.3.220.0. Soon after version 4.5.216.0 showed up through WSUS. I installed it and it installed fine with no problems. Even though it did not prompt for a restart I did it anyway. After reboot version 4.7.205.0 showed up through WSUS. When I told it to install I got the error above.
Because of error 0x80070643 I have completely removed and reinstalled .Net framework version 2.0, 3.0, 3.5 and 4. I have also performed ran a FIXIT to fix software update registration corruption issues. Neither one of these worked either.
I have turned on MSI logging and the only error I see comes from the MPCMdRun.log and it says: ERROR: MpWscUnregister() Failed 8004100E
Anybody have any idea what to try next? Since the update won't install would this qualify for free support through Microsoft?
