1406 error requiring admin privileges to install?

I give up.

I'm trying to install Office 2007 Pro full version onto Vista home Premium.

I have admin privileges but setup fails because of
"Problem Signature 06: Error 1406.Setup cannot write the value command to
the registry key \Word.Document.8\shell\OnenotePrintto"

The only suggested solution is to install programs while logged in with
admin privileges, but I am already logged in with admin privileges and still
get this error. I do not know why setup cannot do what it needs to do in the
registry. This is such a common program to install in Vista that something
must be set wrong on my system, but I cannot determine it.

When I tried to uninstall a trial version of office I got the same 1406
error and could not even uninstall it.

Any help would be very very very appreciated.

Here's a link to the Microsoft supportcenter with one explanation.
There are several, but this due to installing Microsoft Office.

Befor you try Method 1 (Dealing with your registry) try the method 2
deaktivating your spy and adware software (which might be the ones, who don't
allow you to change registry)..

And about being logged on as administrator.
Notice that in Vista, you are normally logged on as standard user, and when
you are to use admin priviledges, you are being asked for.

Finally:
In Microsoft Supportcenter you can always make a search for an error.
Remember, if an error occuring got a number, it is known, otherwise it
couldn't have a number.

I had the same problem with a number of software titles. After pulling all my
hair out and trying to find a way around all the Vista security measures I
started looking at other software on the computer starting with the most
recent install and moving backwards. My first title, my antivirus. That was
my first and last stop. I deleted it and so far don't have any problems. Look
at third party software (antivirus, spyware, etc.)

Please tell me is Error 1406 so important? After pressing <IGNORE> a few times i was able to load my programme. Maybe I am missing something but I don't know what! Isn't Microsoft able to do something a about this error? Is deleting and reinstalling such programmes as AV or Registry Cleaners the only way of solving the issue?

Had similar prob with new updates to office 2003. They wouldn,t install
with above 1406 error.
In the end it was an easy fix, once i knew what to do of course.
Go to your run or start and type regedit . It will bring up all your
registry threads. Yours is the WORD.DOCUMENT. Right click on it and go
to privileges. edit all to full rights and apply. This did it for me.
