MiKTeX and proTeXt ⇒ expl3 | Error during Installation

[leduser]

Hi,

I am not able to install expl3. The error which I get is: Error response from server: 404. I tried even at administrator's level so it is not a matter of permissions. Maybe you know how to solve this problem?

Edit: from nonadministrative level I get error: Unknown archive file size.

I have installed once again and the issues dissapeared.
