Error during installation: Disk1.Cab missing

This is a very strange error because the installer doesn’t save any .cab files during the installation. You will need to delete any files that are left from a previous bad install.
1. Go to Program Manager and uninstall the PresentationPro Express Plugin if it is listed. if you don’t see it, continue to the next step.
2. Reboot the computer.
3. Try reinstalling the Express plugin.
If you get the same error, try installing this version of the plugin. It is the same version of the plugin, it just uses a different installer.
