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.
Note:
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.
