Start Application

The Start Application activity launches an executable file (program) by its name or by the full path, with the startup parameters specified. Using this activity, you can perform any commands as if you were using the OC Windows command prompt. Moreover, it allows you to close applications. Start a standard Taskkill.exe application and specify the required program as an argument. After the activity execution the program will close.
