Font in word don't change between regular and bold. PowerPoint do.

Hi, 

I have install a font from the font book on my mac. The font have both regular, bold, italian and bold+italian. 

I can see and chose the font in my office programmes, so no problems here. 

When testing the font in PowerPoint I can see a clear different between bold and regular text. However, when testing it in word regular text and bold text is shown as the same. 

Any suggestion on how I may fix it? 

Best regard 

Steffen
