Last night I was upgrading our Exchange Server 2007 SP2 to Exchange Server 2007 SP3. All readiness checks passed it and it was ready to go. It stopped all services no problem and made it to the next step then a window popped up saying:
The Installed Product Does Not Match The Installation Source. Select the source installation file. If I hit browse, it wanted the file "exchangeserver.msi" - I tried selecting my SP3 install one and no love, it asked it again.. so I tried selecting the SP2 one and again, no love.
I searched around and wasn't able to find any solutions, so for the sake of not having email down all night, I cancelled the install. Upon cancelling the install, this error started coming up:
The Microsoft Exchange Search Indexer service depends the following service: msftesql-Exchange. This service might not be installed.
I checked and indeed, I can't find that service anywhere,. Now our OWA users cannot search their mailboxes.
So this is sort of a two part question... how do I resolve the source installation error and how can I get the Exchange Search Indexer re-installed/working again?
