Cause

This is due to an issue with Windows UAC (User Access Control) when you are performing the uninstallation as a user who is an Administrator but not the Administrator and are using Programs and Features in Control panel to perform the uninstall.

Resolution

To resolve this issue either:

Logon as the local Administrator account and perform the uninstall.

- or -

Run the installation application (setup.exe) directly and select the Uninstall option. This will correctly elevate the user.
