Office 2007 spell checker not working

Hi all

Spelling Mistakes
For spelling mistakes in Office 2007 there are no red lines showing the
actual spelling mistakes. When I try to run the spell checker it displays
the following error message

“Windows Installer. Preparing to install
Cannot find proofing tools for English (U.K.). If you have the proofing
tools, try installing or re-installing them�


Spaces
If I put extra spaces in the sentences and run the spell checker it finds
the extra spaces in sentences but still displays the following message before
it runs

“Windows Installer. Preparing to install


When I installed Office 2007 I ensured that all files were installed i.e.
“Run all from my computer� option was selected.

I have been through the registry and removed all instances of Office 2000,
the program I upgraded from.


The following registry key does not exist as I deleted it as other forums
have said
HKEY_CURRENT_USER\Software\Microsoft\Shared
Tools\ProofingTools\1.0\Override\en-US

It does not recreate ‘Override\en-US’ after running Word again. Do I need
to create these two folders again and what EXACTLY do I need to put in the
folders?

I have Office SP1 installed as well as the latest Word update.

Any help most appreciated.
