Make sure you are also running Erlang/OTP 25. I will try to make this clearer in the installer!

First, part of my confusion was that the installer effectively asks your OTP path but I think it used to actually install OTP? So I didn't read the dialog carefully and didn't realized it changed, my bad :) But, after installing Elixir and pointing it to the otp 25.0.4 folder. > elixir -v > Cannot find file at 'c:\program files\erl-24.0\erts-12.0\bin\erl.exe' c:\program files\erl-24.0\erts-12.0\bin\erl.exe). This usually indicates a missing or moved file. I install erl-24.0 > elixir -v > Could not load module C:\Program Files\erl-24.2.2\erts-12.2.1\bin\erlexec.dll. I install erl-24.2.2 > elixir -v > {"init terminating in do_boot",{undef,[{elixir,start_cli,[],[]},{init,start_em,1,[{file,"init.erl"},{line,1191}]},{init,do_boot,3,[{file,"init.erl"},{line,889}]}]}} init terminating in do_boot ({undef,[{elixir,start_cli,[],[]},{init,start_em,1,[{_},{_}]},{init,do_boot,3,[{_},{_}]}]}) All the while erl-25.0.4 doesn't seem used (while being in the PATH env), I guess that's the problem but how do you enforce the OTP version? ---- edit: So I kinda made it work. First I noticed that I had erl-24.0 installed by Chocolatey (which I don't remember using ahah) so I uninstalled that. To make it clear, I'm on Windows 7 so the problems may come from that, but maybe it will help somebody else. But then the elixir-websetup.exe (2.2) would not actually complete any longer (while doing so when erl-24 was installed by Chocolatey?), it could not find the actual elixir downloaded installer in C:\<Me>\etc (not the valid user path in Windows 7 but maybe in 10+ ?) I then used elixir-websetup.exe 2.1 and got almost the same error but this time it complained about "elixir-v1.14.1 (Erlang/OTP 25)-setup.exe" while it actually downloaded "elixir-v1.14.1-setup.exe", which I was able to launch myself and finish the setup. And voilà, Elixir 1.14.1 ;)

  This is unexpected. Elixir should just pick whatever Erlang is on the path. This may be a bit too much, but maybe try removing all Erlang and Elixir versions and just picking the latest for both? If you are on WSL, then `asdf` or similar can do the trick.

    See my edit, it works now thanks, I can now try dbg :) (I do use asdf to install Elixir on MacOS and Raspberry though)

      Awesome! Btw, I sent a PR to Erlang/OTP so it raises a better error message when using an old Erlang version. :)
