Finder not working in OSX 10.11.6

My iMac is stuck in a loop of "Finder quit unexpectedly" error boxes. No matter how many times I click to get rid of them, they come right back. I can see my screen background images but can't see my hard drive or any of my files. Finder will NOT work. I have tried Terminal to remove the preferences file, but it says No such file exists. It is like Finder is no longer on the computer. I tried Safe Mode, no luck. I tried Activity Monitor but Finder does not show up in the list.

Am I at re-installing stage? Can you just re-install Finder for 10.11.6?
