AddFontResource/Ex not working on some machines

[Dave Nottage 557]

Some code I'm working with uses AddFontResource or AddFontResourceEx - both return a positive value (in this case 1), so according to the documentation the font is added successfully, however they are not actually displaying correctly.

 

The problem happens only on certain machines, in this case Getac Windows Tablet (F110 and T800 models), but the fonts are displayed correctly using the same application on a Microsoft Surface. All machines are using an administrator user account. 

 

Any ideas as to why it does not work on the machines in question?

Quite possibly depends on the font files as well. Can't imagine this is related to Delphi.

On Firemonkey there is a problem loading fonts dynamically, so maybe its related to that?

Have you tried installing the fonts manually on these machines?

I think you may be right.

No, since the goal is to not have them installed. Having said that, I have a bad feeling that the machines on which it does work may have the font already installed (not sure if anyone actually checked), especially given Hans' answer. I'll know for sure tomorrow.
