This message is generated during diary generation, just before InDesign is launched, but you should have had a corresponding design-time message originating from any of the properties where you can specify a change of font (such as minicalendars and macros).
➢Note that this warning is not the same as the one (shown in the example on the right) that you get when opening an existing InDesign file that contains references to fonts that are not installed on your PC.
The InDesign message on the right will go away as soon as the file is opened on a PC with this font installed.
But the present message that concerns us here, in this topic, means that the reference to the missing font could not be inserted in the InDesign file.
Therefore, even if the generated output file is later opened on a PC that does have that font, the font will still not appear in the document.
The issue usually arises due to the use of some older screen fonts do not have a postscript font name. The solution is to create the file text file OverrideFontFileNames.txt in the folder C:\Q++StudioXV4\ in which you can list the font names and corresponding postscript names of the problem fonts, as discussed in the topic on font name issues.
