Installation failed Error 1603
 

I have uninstalled the software and re-installed and now get this message:

Windows Installer installed the product. Product Name: DisplayLink Graphics. Product Version: 7.0.42631.0. Product Language: 2057. Manufacturer: DisplayLink Corp.. Installation success or error status: 1603.
Software does nt appear to be installed in "Programs and features"

I am using an administrator account and have run a basic registry cleanup.
No improvement
Computer is Windows 7 Pro
