I am stuck here, as I cannot use application modeller to launch a .bat file and then spy the application. I need some expert advice. The requirement is -  Windows Application which is launched from a .bat file instead of .exe, and then spy the launched application.   Thanks   Sun, 11 Feb 2018 08:11:00 GMT https://community.blueprism.com/t5/Product-Forum/How-to-invoke-bat-file-from-the-application-modeller/m-p/58109#M12009 ShibuTewar1 2018-02-11T08:11:00Z https://community.blueprism.com/t5/Product-Forum/How-to-invoke-bat-file-from-the-application-modeller/m-p/58110#M12010 Have you tried launching it via the Start Process action in the Utility - Environment VBO?  The other option is to create a shortcut link (.lnk file) to your bat file which you would potentially be able to launch in Blue Prism. However you start your .BAT launched app - you will then need logic to wait for the application and attach to it.

I passed the ""cmd.exe"" and the path to the .bat file, the cmd prompt is launched but after that nothing happens. I am doing anything wrong here.

What is the steps being taken in the .bat file? Can you launch the application by typing the commands in the .bat file in to a command line and get it to launch. Is the application a Java app? Can you use java integration to launch the app? I would try and answer these questions and see if that help solve your issue.

Yes this is a java application. The bat file is a simple file eg -  start javaw -cp /lib/app1.jar:lib/app2.jar:lib/app3.jar   Mon, 12 Feb 2018 21:31:00 GMT https://community.blueprism.com/t5/Product-Forum/How-to-invoke-bat-file-from-the-application-modeller/m-p/58113#M12013 ShibuTewar1 2018-02-12T21:31:00Z https://community.blueprism.com/t5/Product-Forum/How-to-invoke-bat-file-from-the-application-modeller/m-p/58114#M12014 @Shibu tewar      And all I have same doubt.
