</head><body><p>Hi,</p><p>I am a beginner in erlang and probably it is quite a naive question but I am new to both erlang and linux os as well. I an using Amazon AWS linux instance. I was installing ejabberd in the linux instance through source code when I came to know that I had to install erlang first so I ran command </p><p><code>yum install erlang </code></p><p>and the system installed erlang R14B ,then I found that it was needed that i install erlang/otp 17.1 for this.</p><p>So now I am a bit confused how to uninstall previous version of erlang first and then install a specific version of erlang i.e. Erlang/OTP 17.1 on Amazon AWS linux instance.</p><p>Thanks in advance.</p><p>Regards,</p><p>Abhishek</p></body></html>
