How to use a web font with multiple weights?

I've built a prototype with Axure for a client app, which works alright, but the issue is that nobody else on my team can see the web fonts.

I've tried telling them to install the same font on their machines, I've tried using @font-face and font mapping, but the trouble is, I think I would be able to do this if it were only 1 weight, but the font has 4:

  • Light
  • Regular
  • Medium
  • Bold

And they all have the same name. I know how to do this in 2 min in CSS, but how do I get Axure to do it?

Thanks
