why are arial narrow fonts unavailable in photoshop cc

Photoshop CC 2014? 

What OS version are you running?

I'm running Win 8.1 and it seems to be there for me...

Confirmed.  I tested it on WIndows 7 and the font is missing.

Your sure the fonts are actually installed in C:\Windows\Fonts

If you go to C:\Windows\Fonts and double click on the Arial font group, is Arial Narrow shown?

This sort of explains it: "Arial Narrow" is not recognised as font family by Photoshop Elements (Windows Vista)

Select Arial > Narrow in Photoshop CC and earlier.  CC 2014 will display the Arial Narrow family separately

Photoshop CC/Windows 7

That's intersting.

On this particular windows 7 x64 system the Arial Narrow fonts are listed in both photoshop cc 2014 and photoshop cs6

photoshop cc 2014

photoshop cs6

windows vista x64

photoshop elements 8

photoshop elements 2

Maybe this is the cause and solution?

Arial Narrow unavailable, incomplete | CS applications | Windows

I don't think that solution that i posted will work unless you have office 2007?

Interesting.  The Windows 7 Ultimate x64 VM that I use for testing did NOT have the ARIALN*.* series of narrow font sets installed, nor any Arial Narrow fonts by any action by Microsoft.  It IS fully updated per Windows Update.  Perhaps this says Adobe's statement "The issue has been addressed by Microsoft" isn't completely true regarding Windows 7 systems, at least not automatically so.

After capturing the above, I installed the fonts manually on the test system by dragging them into the C:\Windows\Fonts folder using Explorer (causing an implicit install).  Now they DO show up in Photoshop.
