Hey people,

how would I go about removing erl8.3 from the build environment?
I need to upgrade it to erl9.0

    Hi Daniel,

    You can use this PS script to install Erlang 9.1 during the build:

    Write-Host "Installing Erlang..." -ForegroundColor Cyan
    Write-Host "Downloading..."
    $exePath = "$env:TEMP\otp_win64_20.1.exe"
    (New-Object Net.WebClient).DownloadFile('', $exePath)
    Write-Host "Installing..."
    cmd /c start /wait $exePath /S
    $env:path = "C:\Program Files\erl9.1\bin;$env:path"
    [Environment]::SetEnvironmentVariable('ERLANG_HOME', 'C:\Program Files\erl9.1', 'Machine')
    Write-Host "Installed Erlang" -ForegroundColor Green

    We added an issue to update it on the image:
