SharePoint uninstall - "the product installation has been corrupted, run setup from original source"
"the product installation has been corrupted, run setup from original source"
See this message before? I saw this when trying to uninstall SharePoint from the Add/Remove Programs menu. This happened after someone uninstalled IIS before trying to uninstall SharePoint and then reinstalled IIS.
The suggestion was a good one. After finding the SharePoint source files we ran the setup.exe, entered the product key and let it run. A few minutes later we got a more specific error message:
“Microsoft Office SharePoint Server 2007 encountered an error during setup. An installation package for the product Microsoft Search Front End cannot be found. Try installation again using a valid copy of the installation package 'osrchwfe.msi'.”
Well, that’s a much better error message. Apparently the Microsoft Search Front End component is not happy. Reinstall required. After a quick search through the SharePoint installation source files we find the ‘osrchwfe.msi’ file at \Global\Search\osrchwfe.msi. Double click to run, and a few seconds later it’s finished.
Run setup.exe again and all goes well. Takes a few minutes.
Select remove from the Add/Remove Programs menu and all goes well. SharePoint is gone.
