Elixir command does not work on the terminal

I know you’re probably tired of getting on this question but you’ve helped me before and I promise to actually respond and do what you ask NobbZ so pleeeeaaaase help me. I have installed using both the official site and chocolatey neither works. It stopped working right after I installed postresql, node, and phoenix.

iex --werl and erl didn’t do anything

Using the elixir windows installer
Elixir v. 1.13.4
Erlang v. 24.1.4
ERTS v. 12.1.4
All three bins are in my path enviornment variable

when I type where elixir (or erl, iex, or mix) it says 'where' is not recognized as an internal or external command, operable program or batch file.

Please help me elixir gods
