Try right-clicking the icon, then select "run as Administrator". The problem is that it's installed to your Program Files folder, and the folder is restricted to only be written to from a privileged account.
I've been in touch with the vendor of our update framework, and I've received information to include a fix in our next update which will prompt you to elevate privileges when a new update is available. For now, the right click > run as Admin, or uninstalling and reinstalling should do the trick.
To answer your question though, yes, your hands are still safely stored.
