Running Office 2000 in Windows XP, the help screen in all packages is blank.
The Office Assistant is turned off, the help window opens but contains no
data.

I have repaired Office. I have removed and reinstalled. There has never been
a different version of Office installed on this PC.

I have updated the security settings for MsoHelpAWDlg and MsoHelpKeyDlg as
described in the KB 319956 article and none of it works, although I did
notice two key in the registry for each etnry, there was MsoHelpAWDlg and
MsoHelpAWDlg1 and also MsoHelpKeyDlg and MsoHelpKeyDlg1, so I updated the
security on both.
