Can't add brushes to preset library

[dinkus]

I'm trying to add sets of brushes to my preset library but it won't work. The files load into the preset manager box, but I can't save them. The "Save set" button is not activated (just "Done" "Append" and "Add".) I can use the brushes I add or append during that session, but as soon as I close or restart they are gone. Help? I'm running Photoshop Elements 2018 on Windows 10.

As a work-around, try installing them here:

C drive>Program Files (x86)>Adobe>Photoshop Elements 2018>Presets>Brushes

In order to save any brushes you need to select the ones you want to save in a set.

For example, if you want to save all the brushes, click on the first one to select, then

Shift click on the last one to select all the rest.
