Why do I have to log into administer account in order to update Connection Client app? Why isn't elevated admin password enough?

I wonder why updating connection client is so complicated compared to practically every other Windows application? Updating process will not success unless I log out the user's Windows session and log into their computer as an administrator. All other software updates and installations prompt me to use elevated admin user name and password only but Connection Client wants to do it in a hard way. I wonder why and is there a way do do it smarter?
