Make Adobe fonts work with CSS3 @font-face in IE9

As Knu said, you can use this tool, however it's compiled only for MS-DOS. I compiled it for Win64. Download.

Usage:

1. Place the .exe in the same folder as the font you need to modify

2. Navigate to that directory in the command line

3. type embed fontname.fonttype, replacing fontname with the filename and fonttype with the extension i.e. embed brokenFont.ttf

4. All done! Your font should now work.

You should set the format of the ie font to 'embedded-opentype' and not 'eot'. For example:

src: url('fontname.eot?#iefix') format('embedded-opentype')

I can only explain you how to fix the "CSS3114" error.
You have to change the embedding level of your TTF file.

Using the appropriate tool you can set it to installable embedding allowed.
