zsh: command not found: fly

I got the getting started page running but when I go to deploy it with fly I get this error. Running wsl ubuntu on win11. I tried adding it to path with [this](https://community.fly.io/t/getting-flyctl-command-not-found-error-post-install/4954), no change. Tried the same "fly launch" command on windows, same kind of "fly is not a valid blah blah blah" error. When I installed flyctl (I did it on both WSL and windows after the former didn't work), windows says it was installed to C:\Users\myusername\.fly\bin\flyctl.exe. WSL says it was installed to /home/myusername/.fly/bin/flyctl, then tells me to manually add the directory to PATH. Which I did.
