failed to locate a valid qualifying product (using full ver 2k Standard)

I am trying to move my Office 2K Standard (SR-1) from an
old machine with XP Home to a newer machine with XP Home.
After entering the product key I get a message..."Setup
failed to locate a valid qualifying product on your
machine. Please select the drive where a qualifying
product can be found".

When I look for this error on Microsoft, it refers to
upgrade versions needing a previous qualifying product.
However, this is not an upgrade. It's the full version.

P.S. If I try to set up using "SetupSE" I get
message..."Setup has detected the following problems,
please correct them and rerun setup:
You do not have Microsoft Internet Information Server
(IIS) 4.0 installed...".
Help!
