Evidently there are many others who have the same problem since
the forums have a lot of people writing to find a solution to this
problem.

When opening Microsoft Word 2007 a Configuration window would
pop up and it would take 40 to 90 seconds for the program to come
up. It was worse then some of the Adobe programs.. I'm operating a
Vista Ultimate 64x operating system and thought that might be the
problem. Evidently it doesn't have anything to do with it.

I have been trying for weeks to find the solution to the delay but
have been unsuccessful. I checked the many sites Google brought
up, checked out several forums and went through all the Microsoft
Newsgroups to no avail.

Eureka!!  I finally found the solution. This is from http://uksbsguy.com/

I followed his instructions and IT WORKS!!!!

He is evidently a Microsoft employee.

This is his solution....

How to get rid of the installer / configuration dialog when running Office
2007 and Office 2003 on the same system - for Vista and other versions of
Windows

I have been asked this many times following up on the blog entry Installing
Office 2003 and Office 2007 on the same system where once people have
removed the problem with the End User Licensing Agreement (EULA) appearing
every time they start Office they then get the dialogs below every time they
switch between Word 2007 and Word 2003.

when starting Word 2003

when starting Word 2007

The fix to the problem is very simple as it turns out - simply run the
following commands (by pressing the Windows Key+R or typing it into the
Start/Run command box.  Use the line with Office\11.0 if you have Office
2003 installed and Office\12.0 if you have Office 2007 installed.  You can
use both if you have both installed :

reg add HKCU\Software\Microsoft\Office\11.0\Word\Options /v NoReReg /t
REG_DWORD /d 1

reg add HKCU\Software\Microsoft\Office\12.0\Word\Options /v NoReReg /t
REG_DWORD /d 1

That is it.  Office 2007 might want to have one more spin round the block
with it's configuration dialog box, but that should be it.
