# Validate PanelView Plus 7 Standard applications and Compact Machine Edition applications

When a PanelView Plus 7 Standard application or a Compact Machine Edition application is created, the application will be validated to make sure that it does not exceed any of the limits. Errors or warnings are logged in a text file named '<application name>ValidationResults.txt, in the same location as the runtime application file.

Warnings indicate something that will not prevent the application from running, but may produce problems at run time. Errors indicate the presence of some feature or object that will prevent the application from running at all. If errors are found during validation, the .mer file will not be created. If only warnings are found, the .mer file will be created, but a message stating that errors may appear at run time will be shown.
