During the installation, are you selecting 'Enable SSL connection' checkbox?
De-select this checkbox and try again.
When this check box is selected, the TLS/SSL certificate used in SQL Server must be imported into the Windows local certificate store on the JMP Server host before you run the installer. Otherwise, the JMP server installation process fails with the error "Failed to execute
uem_migrate.bat file," and when you click OK in the error dialog box, installation is rolled back. In a production environment, for security purposes, you would leave this check box selected, but to isolate the issue deselect it and try again.
