Abstract: Diagnostic data-collection software is triggered by a fault in application software running on a client computer. Data gathered by the diagnostic software is transmitted to a computer system of a service vendor. Analysis software running on the vendor system analyzes the diagnostic data and generates recommendations. The recommendations are posted on a vendor-managed website. The client is informed by email of a URL to access the recommendations. After a validation procedure, the client can access the recommendations. The recommendations can include instructions for a human to execute as well as software to be downloaded to the client computer.
