# Hardened Runtime

If the application no longer launches once "Hardened Runtime" has been enabled in the Sidebar, there are a number of options in the "Capabilities" Page of the App Wrapper document window.

#### Using Xojo Script or another "Scripting" library.

First select "Allow Execution of JIT-Compiled code" and try again. If the application still doesn't work, also enable "Allow Unsigned Executable Memory".

#### App uses 3rd Party libraries

Select "Disable Library Validation" and try again.
