I hope that this things will help you to create a Group Policy Object(GPO) but take note, when you make changes to the GPO, these changes are not applied immediately to the target computers, Instead, they are applied according to the currently valid Group Policy  refresh interval. In this scenario, when the program has been published to the users, it is available the next time the affected users log on.
