when i import asset with Package Manager

I’m studing by Unit 1 - Player Control. by this link.
(Unity Connectalt textmulation)
but when i import asset with Package Manager, All the time A warning window pops up.
(Warning - Importing a complete project will overwrite your current project setting.
If you’re not sure what this means, you should switch to an empty project before importing this package.)

So i make a project again, but never import at project.
please help me :frowning:

What “So i make a project again, but never import at project. please help me” means? that warning tells you that SOME of the settings will get override. like for example, in your project you are using net 2.0 but the project REQUIRES net 4.0 the settings get override. Thats why is suggesting to import in an empty project

thank you for answer.

but i don’t know how to make a net 4.0

by any chance, D you know UNITY basic lecture?
