    Have tried to install the Excel Add-In but no luck. It downloads OK, but hits and error during installation. Error message reads in part:
    the manifest may not be valid or the file could not be opened. ---> System.Deployment.Application.InvalidDeploymentException: Manifest XML signature is not valid.
    Uninstalled and tried again but no go!
