Well, thanks for all the information! I'll try to get things right
this time.
Looking at my organiser specification, it says I need Outlook
98,2000,2002,or 2003 to be able to synchronise. From what I read
from your replies it seems that I need not have uninstalled the Office
2007 Home and Student Edition, if I had known that neither Outlook
Express nor Outlook were installed by the program.
I am currently left with Outlook Express to uninstall so that I can
install one of the above versions, as I mentioned, it is not
sufficient to remove Outlook by the "Add or Remove Windows
Components".

Outlook Express being installed should *not* prevent you from
installing any version of Outlook.

What is happening when you try to install Outlook and what version
are you trying to install?

I have a 2002 version of Outlook which I have been trying to install
but again it would seem that it is Outlook EXPRESS that I should be
installing! Another misunderstanding due to me thinking the two
programs are just different versions with Outlook itself being an
extension of Outlook Express. It now boils down to the fact that
I need to remove the latest version of Outlook Express in order
to replace it with the older version. Sorry about the
misunderstanding, I think I now know the differences.
Thanks again for your help, I now need to locate a standalone
copy of Outlook Express!

There is no 'standalone' version of Outlook Express. It is part of the Operating
System. In fact, even including the occasional patches that have come out
for it, it is the same program today that shipped with XP when XP first came
out.

Heck, even the 'Windows Mail' renaming didn't substantially change the program.

If your third party program won't work on XP with OE, you may need an older
operating system.

Has the software ever run on XP? Does it say it is supported on XP? Does
the company who produced it exist anymore?
