You have 2 different versions of an application installed on your workstation and you want to be able to use both versions within Remote Desktop Manager
When you configure your Application Installation Path in File – Settings – Path, separate the 2 paths by a semicolon (;). Remote Desktop Manager will prompt you with the selection list and you will be able to pick the one that you want to use.
C:\Program Files\Appsv1;D:\Program Files\Appsv2
