Can’t Install Exchange 2010 SP1 with Error – Setup previously failed while performing the action ‘Install’

Priasoft Migration Suite for Exchange (PMSE)

You may receive the following error trying to install Exchange 2010 SP1. We sure did…

Error message is as follows:

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

Steps to resolve and be able to install SP1:

  1. Open regedit and browse to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v14\
  2. Look in the installed rolls for a key named Action (in our case it was under the MailboxRole key)
  3. Back up the section of the registry in case you need to roll back
  4. Delete the Action key

SP1 setup should now proceed without any further issues.
