MSAS only runs on installed user profile

When logging on to XP Home SP2 as one of the other 4
users. (All users have administrator access) MSAS comes
up with "unexpected error; quiting"
It runs fine from the user where it was installed.
I tried updated it, that didn't work, then I uninstalled
& reinstalled. I also uninstalled then tried to reinstall
as one of the other users that don't work at which time I
got the following error message.
"Error 1904.Module C:\WINDOWS\system32\hashlib.dll
failed to register. HRESULT -2147220473. Contact your
support personnel."

Microsoft AntiSpyware, in its current version, is suitable
only for a single-user PC running with local Administrator
rights.
