Hi Mike,
What edition of MS Office are you using?
Was it installed from and updated through
an Office Admin point?
Are you using a firewall product?
Are you using a 3rd party download accelerator utility?
If you close Office and your browser then
-clear the cache in your browser;
-delete the contents of the folder
\Program Files\OfficeUpdate11\
and
-cleanup the files in the folder you find by
typing %TEMP% in Start=>Run
does revisiting
http://office.microsoft.com/officeupdate
work?
If not, can you successfully complete a detect & repair
or repair reinstall of MS Office?

HI;
The same is happening to me, this has been happening now
for the last couple of weeks which it hangs at 40% then
gets the following error message.
Error! Unable to check for updates on this computer Help
The Office Update site is unable to check for updates on
this computer. This may be happening because of one of
the following reasons:
You do not have administrative privileges for this
computer.
There is a network problem and the detection catalog used
by the Office Update site failed to download. Go back to
the Downloads home page and try running detection again.
Windows Installer patch files (.MSP files) from
previously applied Office updates are missing from the
\Windows\Installer hidden directory on your computer. MSP
files are stored on your computer after update
installation completes because they need to be referenced
for future update operations. If the files are missing
you will not be able to apply Office updates. You may
also be unable to uninstall Office products as a result
of the same problem. Please contact Microsoft Product
Support for assistance.
You installed Office updates in the past and then
upgraded from Windows Installer version 1.0 to Windows
Installer version 1.1. For more information see the KB
article Windows Installer May Prompt for Install Source
if Unavailable.
I am running XP pro, with addmin rights so don't know
what is wrong, if anyone has any ideas please let me know.
Thanks;
Mike >>
