Can't Install Updates To SR-1 Premium

[Bill]

I use Office 2000 SR-1 Premium,supplied by my office for
work at home on my home computer. Every time I try to
update to SR-1a or anything else, it tells me it can't
because it can't find the Office 2000 product, which is
in the damned CD player. It appears to not like the fact
this is "Premium". Yet when I search for Office 2000
Premium updates, MS support takes me right back to the
same download areas that tell me the CD is "not the right
one." Does anyone know how the to get around this
insanity? Oh, yeah, one other thing: One time I just
tried to install the "Administrator update" for the
Office 2000 Premium product. It downloaded a 50+-meg set
of files, but when I ran setup, it said it couldn't find
a DATA1 install file, and that this problem could occur
if I had at some point done some upgrade path I have no
clue what it is talking about.

Does anyone have any idea how the heck I can do the
updates? I even uninstalled everything, cleaned the
registry (using System Mechanic), etc., and reinstalled
Office 2000 SR-1 Premium, yet the MS Office update site
still won't allow me to install any of the SR or SP
updates ... ???

Thanks much.
