I am using Remote administrator 2.2, when I log on to one of the PC's running this version in the connection info screen as it logs in it says server version 2.1 Why is this? I have checked the exe. in the system 32 folder and it is 2.2
I bet you have the old registry keys still in the registry. Uninstall, delete the entire RADMIN key, then re-install.
You can have 2.1 and 2.2 running at the same time (on different ports or one fails to bind). It's actually a neat way to spy on people. You put 4888 as 2.1 and hide the icon, then install 2.2 on 4899 and keep the icon visible.
