I'm a teacher, currently running PSE 2018. School just installed Windows 10 with PSE 2019. Most of my students don't have it yet, so can I install 2019 on the same computer safeky, or should I uninstall 2018?

It is perfectly safe to have both programs installed on the same computer.  They operate totally independently.  However, you should not have both open at the same time.
