Go back to whoever licensed the font to you and request the .pfm file that goes with the .pfb file that you have. The built-in font installation capabilities of WIndows requires both the .pfb and the .pfm file for each Type 1 font. Even Adobe's Creative Suite applications and Acrobat require both these files. If they cannot provide the .pfm file, demand a refund!
The long-defunct Adobe Type Manager product did have the capability of creating a .pfm file if you had not only the .pfb and the .afm file, but also a matching .inf file. That website you visited is at least eight years out of date in terms of its information. Do not attempt to load any version of the Adobe Type Manager on Windows XP 64-bit or any version, 32-bit or 64-bit, of Windows Vista or Windows 7. You could end up with a damaged Windows installation requiring reinstallation of Windows.
