For reasons I won't go into, I needed to install Word 2000 (part of Office 2000 SR-1) under Windows 7 (x64). It installed, and Word launched - but there were no icons & it hung.
I found a solution in a PC World Forum (http://forums.pcworld.com/index.php?/topic/73733-microsoft-word-2000-in-windows-7/page__gopid__381736entry381736): one person got it to work by uninstalling Windows Live Add-in 1.3 and Office Live Connector.
I didn't have Office Live Connector, but I did have Windows Live Add-in. I uninstalled the latter, which I don't need, and Word began to work.
Next I'll see if I can re-install Office 2010 (minus Live)and get the two to live together.
