New install of 2020, upon start up I get a dialog box saying no textures, then no 3D. 

It gets annoying having to close these boxes each time I use Softplan. How can I change this

from happening?

On the Help menu, select Download Additional Content to download any libraries that did not install as part of the initial program installation.  The Download Additional Content button should also appear on the Symbol Selection dialog if not all libraries have previously downloaded.
