topic Have you done some in Product Forum https://community.blueprism.com/t5/Product-Forum/Change-setting-of-start-file-of-business-object/m-p/48227#M3798 Have you done some Application Assessment experimentation yourself to see if it is possible? If you launch your mainframe using the BAT file (using the Start Process action in the environment VBO), are you then able to attach your mainframe object to the running emulator instance?

What methods have you tried to attach with? BP provides different ways for this to perform either via process name, via launching it or via window title. -Dex Fri, 03 Nov 2017 19:46:00 GMT https://community.blueprism.com/t5/Product-Forum/Change-setting-of-start-file-of-business-object/m-p/48229#M3800 DexterWhelan1 2017-11-03T19:46:00Z
