We are applying Exchange 2007 Service Pack 3 on an SBS 2008 server and received the following error:
Exchange Server 2007 SP3 Setup
Error: Setup cannot continue with the upgrade because the ‘DataCollectorSvc' () process (ID: 1564) has open files. Close the process and restart Setup.
So, we brought up the Task Manager and opened Processes tab:
After right clicking on the DataCollectorSvc.exe and clicking on End Process we clicked the Retry button in the Exchange SP3 Setup.
We are good to go!
