Exchange 2010 SP1 Fails

Posted by Alan McBurney on November 16, 2010

Recently while patching Exchange 2010 servers one Mailbox server failed to patch throwing the error

Some controls aren’t valid. Setup previously failed while performing the action “Install”. You can’t resume setup by performaing the action “BuildToBuildUpgrade”.

The solution was a painless affair

Open up registry editor…

  1. HKLM\software\microsoft\exchangeserver\V14\
  2. Export Key hive for backup.
  3. Look in each “role” folder (MailboxRole, HubTransportRole, etc) and delete any key labelled “Watermark” and “Action”

Setup completed after performing the steps above.

    Thanks for this. I had an issue with /m:RecoverServer because I had tried an uninstall first and it set the keys as well. So this got me out and into being able to recover! You RAWK!

  2. This same issue happenes to me when upgrading exchange 2007 to SP3 before migration of server to Exchange 2013.
    Same thing fixes the issue in Exchange 2007 as well as 2010. Just need those registry keys deleted.
