Since I updated to the 2021 version, I keep getting the components installation screen. ALWAYS. I don't want to install anything else but it keeps showing up.
I suspect the reason you continue to see this screen is because you have not chosen to install e.g. the "Demo project". Is there any particular reason why you have chosen to not download that project? It really is quite small, in case this is a disk space issue.
I remember this "problem" has been raised before in a post to the forum, though I can't now find it!
. . . . already installed Fade effects. But keeps showing me the screen after startup . . . .
You should see this dialog when the program starts - if you do not open the Program settings and on the System tab click the Reactivate dialogs option and restart the program - then click the options shown below
