= phenomenon =

Builds of Virt Viewer for Windows OS are hosted at [https://fedorahosted.org/released/virt-viewer/]. These builds are distributed in the form of msi files.

When these msi files are downloaded, the web server sends a MIME type of "application/x-troff-man" which is incorrect.

When a user with MS IE downloads one of the msi files and receives the incorrect MIME type, it changes the filename extension from msi to man. The user cannot install the program unless it is renamed back to msi.

My university uses RHEV for virtual desktops and ask our users (in certain cases) to download these msi installer files.

= reason =

This is a known issue with the mailcap file used by httpd in Fedora. See the Document Foundation mailing list post at the following URL:

= recommendation =

Adjust the web server configuration to send a better MIME type for msi files. A recommendation is made in the mailing list post referenced above.
