no longer able to instal windows elements 6, is this the right upgrade?

getting the “not safe to open” when I click on set up file, assuming it’s too old, want to be sure I get the right upgrade, is this the right one, for 20$ I have/had elements 6.02 before?

If you had Cubase Elements 6, then you should pick the 2nd option:
Update from Cubase Elements
