Default Unable to install/uninstall office 2007 Professional Trial (OEM)

If your previous Trial has expired, attempting to install a different
version Trial will fail, in so much as that too will show as expired.
When you have the actual Office cd, BCM is on the second disk, and has to be
explicity installed, once youve installed disk 1.
I dont know whether the trial version is supplied with two installation
files, one being for office, the second being for BCM - The err msg appears
to suggest Office has not been installed, and you are trying to install BCM
only.
Purchasing a product key from MS to convert a trial is more expensive than
purchasing the complete pkge from eg Amazon

As with many people I have had a copy of a Microsoft Office 2007 Trial
installed on my computer by the manufacturer.

I uninstalled this version and tried to install the professional trial
instead (I intend
to purchase a product key to convert this to the full version but won't do
this till I can guarantee it will actually install) and recieved the
message:

'Microsoft Office 2007 must be installed before you can install Microsoft
Office Outlook 2007 with Business Contact Manager. Install Outlook from
CD1,
and then start this installation again.'

From a search of Google I determined this means I have to uninstall my
copy
of office... but I already have uninstalled it. I'm kindof stumped at
this
point I guess the installer is looking at a registry key or something
which
I've missed in my attempt to fully uninstall this software.

I have tried the following:

1) I have followed the manual uninstallation instructions given he
http://support.microsoft.com/kb/928218/en-us and the problem persists.

2) Spent hours searching my registry for any reference to 'Office', gone
into every Microsoft folder and deleted anything which looks related to
office (this includes the keys listed in the manual removal knowledgebase
article).

3) Uninstalled the activation helper and deleted any reference to it I can
find.

4) Deleted every folder related to office that I could find.

5) Ran registry cleanup software.

6) Ran 'fix it for me' and was told that the wizard was incompatible with
my
system or version.

7) Downloaded software packages promising to remove office (some of which
turned out to be trojans - I knew there was a chance of this but I'm
desparate).

Any suggestions would be appreciated.
