Unfortunately, during the uninstall process or lack thereof the STBSuite has been left in the Windows System Registry.
You will need to remove information contained in the Registry. To accomplish this you will need to launch the Registry Editor – this can be done by clicking “Start”, then “Run”, then typing in “regedit” (without the quotes). Once the Registry Editor is up, open the folder HKEY_LOCAL_MACHINE\SOFTWARE. Locate the STB folder and then right-click on it. Then click “delete”. Now you can run the new install without any problems.
