When attempting to install a module to a client machine using a ClickOnce deployment, the Cannot Start Application dialog may be displayed with the message: Application validation did not succeed. Unable to continue.
This error occurs when a deployment file for the application is modified after the deployment was created. To resolve this error, you must create a new deployment of the application using the Deployment Wizard. See the Updating or Adding a Deployment Instance section of this module reference guide for details.
When updating an existing deployment, make sure you select the appropriate module, as well as the Instance Name that corresponds to the instance that generated the error.
