Bot sure, but I think if you use the name="Microsoft.Windows.Common-Controls" version="6.0.0.0" setting then it will use themes. Try removing that from the manifest and see what happens. see https://msdn.microsoft.com/en-us/library/windows/desktop/bb773175%28v=vs.85%29.aspx[^] for further information.

A bit of History These days it is quite simple. A lot of the complication about fonts arose during the 1990's, the Font Wars. Various companies claimed copyright over their named fonts. That is absolutely No problems if the fonts you use are on the same computer that you write your software on, Your Computer. Difficulties arise however, if you write a document in a set of fonts, try to load and print it on another computer, which may not have a Font installed by the same Name. Microsoft tried to resolve the issue, by trying to get the Closest Comparable Font. and included a structure which contains obscure Font designer Lingo terms, such as 'Internal Kerning'. That War was won by Microsoft, Fonts can now be downloaded for free. Things have simplified by now. Just specify Type Name, Style (Straight/Italic/Bold) and a Point Size. That is all that is required these days. Regards :) Bram van Kampen
