Hi John,
I too was getting the same "Class not Registered". Your screenshot mirrored my Speccy summary page exactly.
(This is the first time I've tried Speccy, so I can't comment on the older version.)
My issue turned out to be- Windows Management Instrumentation,aka: WMI, when accessed, came back with
"Can't collect Information"--see attached pdf.file.
Turns out my WMI (which stores All my computer's nfo-drivers,file associations, permissions, programs, what does that with who and when-everything about my OS) needed to be repaired.
My WMI is back, and I've noticed a dramatic improvement in performance (my wife would probably disagree on this).
Just installed Speccy v1.02.156, and it is working fine.
Enclosed are a few links to MS Tech about WMI, troubleshooting, repairing, and a diagnostic tool from Microsoft(Thank you, Uncle Bill!!).
Hope all this rambling helps- Good Luck, keep us posted on what you find.
My OS- XP Pro. sp3
