As per the Erlang/OTP 26.0 release notes, “werl.exe has been removed and replaced with a symlink to erl.exe”. rebar3 will probably need to be patched, but it needs to keep compatibility with OTP 24 and 25, too.

Thanks!

I was trying to fix by changing the script to point to erl.exe instead of were.exe. .cmd console was not working.
