Error: The install in progress conflicts with a previously installed Microsoft Office 2010 Server product (FIXED)

I came across this error when doing a re-install and wanted to post it in case this helps anyone else. The root cause was that I had uninstalled SharePoint Server 2010 without first uninstalling Office Web Applications.

  • Downloaded Windows Installer Clean Up utility (msicuu2.exe)
  • Highlight any rows beginning with “Microsoft Office Web App …” and click “Remove”
  • Reboot
  • Run SharePoint 2010 install again
