Assume you want to uninstall Microsoft Office SharePoint Server 2007 from your server to re-install the SharePoint binaries. In this situation, when you click the uninstall button or the change button in Add/Remove programs, you receive the error message.
Before you begin the manual uninstall procedure, ensure that you have taken a working backup of the databases and the farm and that you disconnect the SharePoint server from the existing farm either by:
>> Running the SharePoint Configuration Wizard and disconnecting the SharePoint server OR >> By running the following command: psconfig –cmd configdb -disconnect
To uninstall SharePoint Server 2007, click the Fix it button or link. In the File Download dialog box, click Run and then follow the steps in the Fix it Wizard.
This wizard may be in English only. However, the automatic fix also works for other language versions of Windows.
If you are not on the computer that has the problem, save the Fix it solution to a flash drive or a CD and then run it on the computer that has the problem.
