Installing Erlang / RabbitMQ on Windows 10 64-bit

Question

I would like to install RabbitMQ on my Windows 10 64-bit PC.

The RabbitMQ installer reports that it requires Erlang to be installed.

I downloaded the erlang installer (OTP 19.1 Windows 64-bit Binary File (101629312)) from http://www.erlang.org/downloads . When I run it, it displays a dialog that reports "Error opening file for writing: C:\Program Files\erl8.1\Install.exe" and gives me the option of "Abort", "Retry", and "Ignore".

(Surely this installer is supposed to place files in "C:\Program Files\" directory rather than read them?)

If I click "Ignore" in the dialog, the installer appears to be working, and I get a good few subsequent dialogs, in all of which, I click "Ignore".

After the Erlang installer has run, I attempt to install RabbitMQ installer again but it reports that it requires Erlang to be installed.

Can somebody please help me?

Am I wrong to expect a software installer to "just work"?

Thanks in advance.

Answer 1

You need to run your installer "As Administrator" (right click on the executable).

Since it tries to write in your ProgramFiles folder, your regular user rights are not enough (which is actually a good thing since that means you do not live constantly with Admin rights).
