While troubleshooting an error dialog stating “the trial period for this product has expired” that started appearing, I uncovered a potential solution is to re-run the SharePoint 2010 Products Configuration Wizard. Unfortunately, that just ended with it being stuck at 10% on configuration task 10 of 11, displaying “Upgrading SharePoint Products… The farm is being upgraded in the timer service process. The task is 10.00% completed.” The additional task the result of the installed Office Web Apps 2010.

I then opted for the best solution – uninstall followed by a reinstall of SharePoint Server 2010. I uninstalled both SharePoint Server 2010 and Office Web Apps. They appeared to uninstall successfully, but when trying to reinstall, the following error dialog appeared: “The install in progress conflicts with a previous installed MS Office 2010 Server Product.” Turns out that this error has to do with the Office Web Apps not completely uninstalling.

To fix the uninstall, the recommended solution is the now defunct “Windows Installer CleanUp Utility.” Microsoft has expired this product as it may cause damage to the system. This has been replaced with a Microsoft Fix it utility to uninstall Office.

When trying to run the Fix it utility for Office 2010 suites I ran into yet another error – “The system administrator has set policies to prevent this installation.” This occurs because it is not run with administrative privileges. The easiest solution is to run a command shell as administrator and run the MicrosoftFixit50450.msi installer program in the command shell. This ran successfully and enabled the successful re-installation of SharePoint Server 2010.
