Photoshop CS4 not loading all fonts

I'm running Photoshop CS4 on WinXP and I have been sent a PSD as well as the needed fonts. I have installed all the fonts I got into the Windows fonts directory.

When I open up the PSD in photoshop it tells me I am missing some fonts, then when I go to click on some text it tells me you are missing Roboto Bold or Roboto Regular.

I then go to the windows fonts dir to confirm all the fonts are there and they are.

See below..

It seems the font list in PS shows most of the above fonts, but not all, and conveniently the ones that the PSD uses are included in the ones that aren't loading.

The ones that aren't loaded are:

Bold
Bold Italic
Condensed
Condensed Italic
Regular
Italic (Regular Italic)

Well, of all the things I tried the only thing that worked for me was to put all the fonts (.ttf files) in the following folder:

C:\Program Files\Common Files\Adobe\Fonts

I didn't have this folder, so you may need to create it.

Hope this helps others!
