I have a SharePoint Server 2010 installation which had some problems. A backup was made of the SP web applications, and SharePoint was uninstalled, then reinstalled. Unfortunately, it also had Office Web Apps installed, and things weren't done in the right order. Now I need to install Office Web Apps again, but can't as the setup program stops with this error message:
Microsoft Office Web Apps encountered an error during setup.
Could not open key: UNKNOWN\Components\97E764D0FEBDA2744ACE799C10C3D8E9\00004109441100000100
Verify that you have sufficient access to that key, or contact your support personnel.
Has anyone encountered this? Is there a list somewhere of the steps needed to manually remove all traces of the previous installation of Office Web Apps?
Thanks in advance! :) Thomas
