Fonts aren't installed for a program, fonts are installed on Windows, and all Windows programs use them.
So just install one of those old True Type fonts via Config Panel and see if Wordpad picks them up. If so, do the other ones. Let's hope the diskettes are still readable (that's the only issue, I think).
Using XP home, SP2 all updates.
HOW do I add fonts to WORDPAD?
What type of font is required? True Type?
If TT will work, can I use TT fonts that I used with Win98? (lots of old TT fonts saved to floppy)
