Deployment exit code 1619 is a MsiExec error, not a BatchPatch error. From the Microsoft documentation:”
ERROR_INSTALL_PACKAGE_OPEN_FAILED
1619
This installation package could not be opened. Verify that the package exists and is accessible, or contact the application vendor to verify that this is a valid Windows Installer package.
If you’re a customer with active support and you want to troubleshoot this further, we would need to see the full contents of the batch file, as well as a screenshot of the deployment configuration, and a HTML grid export. In that case, please contact us directly so that we can get those things from you.
