During one of our shows, Kelly had called and said she was having problems installing Microsoft Office 2000 on Windows Vista…
Per http://support.microsoft.com/kb/932087 (Description of the versions of Office that are supported on Windows Vista):
“Because Office 2000 and Office XP are in Extended Support, there have been no fixes for issues that occur when these products are run on Windows Vista…”
I recommend she:
uninstall ALL products related to Microsoft Office…
restart the computer…
and attempt to install Microsoft Office 2000.
