To install PostScript Type 1 fonts on Windows PCs, you will need the *.pfb and corresponding *.pfm-files. Adobe Type Manager used to create the *.pfm-files automatically. Have a look in your old Windows-XP-font directory for them. If you don’t have the *.pfm-files, you can use the *.afm and *.inf-files to create them. There is a free tool called “afm2pfm” for this purpose. I have sent you a PM.
