Hello,
I am an Adobe employee working on the issues surrounding the download manager to download Adobe Reader.
The team is aware that some users are having difficulty downloading Adobe Reader due to an error message, "metafile download failed".
If you are one of the users having the problem of "metafile download failed" error message, please send me a private message with your email address so we can contact you.
Thanks,
-Yuko C.
