If you’ve already downloaded the SP1 bits for Configmgr and Endpoint Protection 2012 you’re going to want to download them again. In a late blog post on Friday, Microsoft have indicated they have refreshed the bits to fix some corruption issues and add a client fix.
Per the blog post:
The binaries for System Center Configuration Manager 2012 and System Center Endpoint Protection 2012 have been updated to correct some minor issues. The binaries have been updated at the Download Center, and also on the Technet and MSDN download sites. For Configuration Manager 2012 SP1, the updated download release of SP1 includes the following hotfix:
Installation error 0x800b0101: System Center 2012 Configuration Manager Service Pack 1 client
For Endpoint Protection, the new binaries include fixed files (Linux/iOS) that were corrupt in the initial release.
MSDN Download Link:
Technet Download Link:
Microsoft System Center 2012 Service Pack 1 Configuration Manager – Clients for Additional Operating Systems
This means if you downloaded the binaries prior to today (1/25) – you will likely need to re-download them.
P.S. This is by no means the ultimate fix to all the growing issues around the release of Service Pack 1 for System Center 2012. Rumor has it that SP2 is in the dev cycle already. No word as to a release date.
