Yes, you're correct. It looks like the typeface that corresponds to NI Dialog has changed in CVI 2012. This is something that should have been explicitly called out in the readme, and I apologize for that oversight.
NI Dialog is, by design, a "variable font". That mean that it's a font that can correspond to different typefaces in differect computers, since it's tied to an alias (DEFAULT_GUI_FONT) that can resolve to different actual fonts in different computers, different OSes, and potentialy (as in this case) different versions of the CVI runtime. What happened in this case is that a bug was fixed in CVI 2012 in that CVI was previously not taking into account the Microsoft font substitution table:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes
Going back many years now, the DEFAULT_GUI_FONT has corresponded to MS Shell Dlg. It seems to me that MS Shell Dlg is somewhat obsolete and so it turns up in the FontSubstitutes table above, so that applications to replace it with something else. In my PC, that becomes "Microsoft Sans Serif". Before CVI 2012, it was incorrectly not being replaced with Microsoft Sans Serif, whereas now it is.
Sorry about this.
