I think its not possible to copy the Font file to the font-folder with out adminstrator status. so i decided to use an application manifest to run my program as a adminstrator on startup.

Can someone give me some help on this please, since i dont know what i am doing wrong? I used a messagebox to have a quick look at the permmission i requested and it says i asked for write permission for C:\Windows\Fonts and read permission for the folder in "origin". Is there something else I have to do?
