Hopefully you did not try to install the old Adobe Type Manager software. If you did, you may need to totally reload Windows if you cannot restore your system to its state prior to attempting to install that software!
Assuming that you didn't make that fatal mistake, the method for installing Type 1 fonts, each of which consists of a .pfb and a .pfm file is as follows:
(1) Copy the .pfb and the .pfm files to a single directory if they are not already so available.
(2) Select the .pfm files for the fonts you wish to install.
(3) Right-click and select Install which will then proceed to install the fonts onto your system copying both the .pfb and the .pfm files to the C:\Windows\Fonts directory. Do not drag-and-drop these files! Alternatively, if you don't want the font files themselves resident in the C:\Windows\Fonts directory, when you right-click the files, select Install as shortcut. This installs the font but references it from its current location.
