Parameric eq or design notch filter

Hello all, trying to do FR equalization I have windows XP computer so minidsp will not work. REW also will not work. Dirac live also seems not compatible

Trying to find a different XP friendly DSP system or if that fails a notch filter program to design passive eq using caps, etc.

I have found SoundEasy and Ultimate Equalizer web page. This site is intended to provide information about our WinXP™ program:Bodzio Software but can't figure out what it is I am buying or using?
