Microsoft released Update Rollup 2 for System Centre 2012 SP1 a few weeks back but with this release there was one missing component – VMM. Last week Microsoft updated RU2 to include the fixes for VMM 2012 (under the KBs KB2826405 & KB2826392).
It is worth noting that you MUST uninstall VMM RU1 before you install this RU2 release, this is due to a problem with the original Update Roll up 1 and the way the files were packaged.
If you download RU2 from the Microsoft update catalogue and have already manually installed it, you must uninstall RU2 then uninstall RU1 and reinstall RU2 again. If you use WSUS for your updating you won’t receive RU2 until you have manually uninstalled RU1.
Microsoft has released an apology for all this installing and uninstalling you have to do:
‘We apologize for any inconvenience this causes your organization. We have performed cause analysis on the issue and have established processes to prevent future recurrences of this situation.’
