I thought I was downloading Libre Office to my laptop, but only got Writer and Calc. I can’t seem to find out how to get Impress.
Can you tell us your OS and the version of LO?
Some Linux-distributions may not install all of LibreOffice (several remove Base).
.
Then check, if you can open an Impress file via menu: File>New-> Impress or Presentation
If this works, all you miss is desktop Integration, and Impress is already available.

Impress is there. I just had to learn how to find it. Thank you for your help. Much appreciated.
