I have a program written in Java that is in use by many customers. One customer is receiving the following error when installing my program. Does anyone know what would cause this?"Module [Path]\JavaWebStart.dll failed to register. HRESULT-2147220991. Contact your support

Sounds to me as if the JRE of the customer is corrupted so the webstart capabilities are broken.Try to reinstall the JRE on the customers machine. If that wont help, give us some more information please.Bye Schippe
