What a strange problem... I can only give some ideas, maybe you already tried them but anyway:

Try to install the same old version that you once installed correctly... maybe newer installers have some change.

Check you are installing the 32bits, or the 64bits, depending on the machine you have.

Before running the installer, make sure erl.exe, werl.exe or any other program related to erlang is not running.
