Error 1935 installing Outlook 2007

[A Lake]

I'm running Office 2003 (including Outlook) on a Vista SP1 machine. Installed
Office 2007 and left Outlook 2003 running.

Now I wish to upgrade Outlook to 2007 but its impossible. Removed Outlook
2003 and every time I try to install Outlook 2007 I get the Error 1935
(0x80131047) message.

None of the .Net fixes on the MS site are of any help. (how are you supposed
to reinstall .Net 2.0 when Vista has 3 built in?!) Having searched the web
this error seems to be the end of the line for installing Office 2007, has
anyone managed to do this?

Much of what I read suggests this error can result from having an AntiVirus
or AntiSpyware application active during the install. Is it possible you
have such a beast?
