Dear R Kelly,
My hard drive is 285 GB and has 205 GB free. pse 2, pse 4 and pse 8 all worked OK on my old PC with a similar size hard drive and Windows XP, but were installed in version order starting with installing pse 2 and ending with installing pse 8 as they were released. I originally installed all 3 on this PC but pse 2 was accidentally removed by a PC clean-up program.
Regards John Weyer.
