module.info file

Hello
I try to install usermin-webmail-1.420 since a couple of day and i invariably have the error missing a module.info file. Is it a misconfiguration of my server?
I found nothing about these error on sourceforge usermin board.

How did you install it?

tried installing by local file, URL and uploading.
same issue.
