The thing is, when i install these fonts, they work OK. But, for some reason in the fonts directory, they're named like: %segoe_ui% %calibri% etc. And i was fine with it up until today. When i realized Autocad 2009 is denying to work, i found out that it was something with the fonts, moved them to desktop then after moved back, everything was back to normal. I think some registry key was not functioning right. I'll look in to it later (: Just to let you guys know. (: -- Update -- Here is the screenshot f the corresponding registry entry, after a successful and fresh installation. And this a part is from HiveSft.inf file. Comparing to rest, it all seems normal.
