Font Installation not Happening

Question

I realize this is more of an encompassing "Design CS4" question, but since there isn't a forum dedicated to the package as a whole... .  I am having serious difficulties with installing fonts to the design software from my computer (Control Panel).  I have tried to use ATM Light, but no go, the fonts I need to install are not showing up!  I had no problems installing Helvetica PostScript fonts, but the Helvetica TrueType fonts are not installing (see attached screen shot).  I have tried installing them directly from my computer and again from the Helvetica font CD.  I am on a PC, using CS4.  My coworker (same setup, same software) had no trouble at all installing these fonts.  My network administrator has no idea what the problem could be and has all but given up on trying to help me.  Unfortunately, I am on deadline with several projects that need to utilize the Helvetica TrueType fonts.  If I need to clarify this issue a bit more, please let me know.

Answer 1

Well, when I said that multiple formats of identically-named fonts are a source of issues, I wasn't kidding.
1) Tell us your OS! It matters.
2) Yank all Helveticas from your machine
3) Try to copy (not install) straight from the disk to your \Adobe\InDesign CS4\Fonts folder
4) If they all show up in ID, you know that they're successfully being copied off the disk.
5) If they don't all show up in ID using this method, you know it's not a PS-fonts-versus-Windows problem. (InDesign doesn't use the parts of WIndows that handle fonts; Adobe wrote their own font-handling stuff.)
Nos. 3-5 are meaningless if you are unsuccessful in completing no. 2.
Oh yeah, are you sure they're not installing? Font naming conventions are odd sometimes, and your 55 Roman Italic might be showing up in InDesign as a separate font, or as a style of Helvetica. (If you still have Helvetica truetypes installed and this italic face is one of your Postscript faces, then that's your problem right there.)
