I just got the notification that there is an update avaalible.
So I then downloaded the latest version but when I go to install it , it won't allow me to get past this screen.
So at some point in the past you must have installed version 17.1, but you are still running 17.0.
Multiple versions of Toad can exist on your PC at the same time.
Yes, that is what you have installed.
I would for sure un-install the trials. No need for those if you have a license. It's totally up to you if you keep old versions around.
