When installing vRanger you encounter an error stating the the Quest Sowftware License Service has failed to install. Clicking cancel causes the installation to roll back.
Looking in the Windows System Event log you will see a MSI installation error. The detail will indicate that
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\0B48A4A27A20DBC4EBB5EE690C1599F4 contained incomplete data
This may be due to a failed uninstall or a previous version of vRanger
Deleting the registry key and rerunning the vRanger install will allow the installation to complete. The registry key is recreated with the correct information.
