.reg file downloads from web site as MP3 in Internet Explorer?

Question

I have a custom .reg file, which is used to apply registry adjustments. Making it a download is causing Internet Explorer ad FireFox to treat it as a media file, or download it as an MP3?

Has anyone seen this before?

Answer 1

Figured it out. Needed to add MIME type support to my Apache Web Server:

Using the following configuration:

AddType text/plain .reg

Answer 2

I changed .htaccess to:

AddType text/text .reg

It did the trick for Firefox and IE. In IE I didn't even have to download the file. Clicking it sent it directly to the registry (after ample warnings). When I changed it to text/plain it appended .txt in Firefox.
