I want to run a project using batch file, neoload should run in background. Please help.
You should look at the NeoLoad documentation here. It is explained how to start NeoLoad using the command line.
Basically, instead of using "NeoLoadGUI.exe" to start NeoLoad with the UI, use "NeoLoadCmd.exe" with the "-noGUI" option to run it without the UI.
See the documentation for all the possible options.
