I got it sorted out just to have it gone after a few days. However, I use mostly paint.net for minor imagary and it shows all the fonts and previews; these guys perhaps know what is cooking. I use Inkscape for vector design and it shows all the fonts but not the font preview. It is a pain in the back but as said, I use piant. net for the preview and then choose the correct font in Inkscape.
Microsoft needs to have this fixed. The "work arounds" is not the default way of doing things. And if a Microsoft person try to reply with a solution, make sure your solution works - do not waste our time...
