Weird font error with NT 4

I am testing my installer on a bunch of different Windows platforms. They all installed my app OK, except for NT 4. It seemed to install fine, but when I open my application there is no text. I checked the fonts that I use in Control Panel --> Fonts. The fonts are there, but when I double click them the sample text is empty 🤪! I am using the font.dll with registerfont and unregisterfont. I attached a copy of my nsi for the NSIS gods to laugh at 😞. Anything would be helpful!

Try that again...

If it is not in the default Windows' directory wirte it's full path!

Since it is in the Windows' font directory try writing just the font name. I will check later, when I get back on my copmuter, on MSDN, maybe it says something on NT4.

I think this problem is related to the "When to register locked font?" post. If you have this problem, check there.
