We’ve had an issue for a wee while now whereby if you were using Internet Explorer then you couldn’t use the Download links in the Media Library to download a file. With a little insight from TERMINALFOUR and a poke around in the configuration settings this issue has now been resolved.
The problem
What happened in IE was that if you clicked on the Download link (either when right-clicking a Media Library item or while modifying a Media Library item, see screenshot below) then a blank page would open.

It worked as expected, however, in Firefox.
The solution
It turns out that the solution can be found within Site Manager handlers’ configuration (TOOLS > CONFIGURATION > Handlers tab).

Site Manager configuration
- Go to TOOLS > CONFIGURATION.
- Click on the HANDLERS tab.
- Locate the Download Handler.
- Click on Configure.
- Make sure “Download Method” is set to Attachment.
- Click UPDATE.
The problem was that our Download Method was set to “Inline”.

Interestingly, there’s a letter answered in this month’s .net magazine about a very similar issue involving the content-disposition HTTP header.
Thanks for the tip I have changed ours as well.
