Getting error when uninstalling / installing FileSite: Error "1720. There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Custom action DefineOfficeInteger.

Found that the Windows Management Instrumentation Service was disabled in Services.msc. Enabled WMI and then uninstalled with no errors. Also try:

net stop winmgmt
rd %systemroot%\system32\wbem\Repository
net start winmgmt
restart workstation

Sometimes the WMI repository gets corrupt and needs to be deleted. Upon starting the service, the repository will be automatically rebuilt.
