Some of the fonts can't be read. The fonts are from Adobe Font Folio. I've noticed that the ones which can't be read are ones which are missing a .inf file. What is it for?
So you only really need the inf file when working with PFM fonts or when certain applications require it.
A majority of the fonts are Open Type Fonts (.otf) which are compatible with windows 7. The test are True Type Fonts (.ttf) which are also compatible with windows. If you are missing a font that should be installed, you can find the font file and double click on it to preview the font and then install it.
If you bought this recently, you can contact Adobe support to help get the fonts installed. You may have to re-download the files.
