Vista - Office 2003 Vista"End User Licence Agreement"

I have a laptop which had Office 2007 trial installed. I've manged to
unistall this and install my 2003 version. Everything works ok except for an
"End User Licence Agreement" window appears. I "accept" and continue with
what I want to do. I don't use the laptop too often, but it does not seem to
be asking me to register and never denies me access - just forces me through
this annoying step. What is it and how can I stop it from happening?

See the Microsoft Support article, "You must accept the Office End User License Agreement every time that you start an Office program".

(excerpt)

To resolve this behavior, follow these steps:

1. Log on to the computer by using a user account that has administrative credentials.
2. Start an Office program, such as Word. The End User License Agreement dialog box appears.
   
   Note For Windows Vista, click Start, click All Programs, click Microsoft Office, right-click an Office program, click Run as administrator, and then click Continue.
3. Click I Accept.
4. Exit the Office program that you just started.
5. Repeat step 2 to step 4 for the other Office programs that still prompt you with the EULA.

I have had this problem too so I took your advice. However, I cant find the Office 2003 files. I checked the shortcuts to all the programmes and it says the target is "Mircosoft Small Office Business Edition 2003" but I can't find that under Microsoft in Progam Files. For some reason Publisher is there but not Word, Exel, or PowerPoint.
Where would I look for them?

You got a point there. I cannot use the "Run As..." command for Microsoft Office shortcuts in the Vista Start menu either.

To find the Microsoft Office 2003 program files I right-clicked the "C:\Program Files" folder and searched for winword.exe, which found the file in C:\Program Files\Microsoft Office\OFFICE11 folder. Here I can use the "Run As..." command directly on the executable file itself.

Hope this helps!

Thanks for that. I actually got some advice on how to do it through the registry by allowing full permissions and agreeing the licence while in that state. I then removed the permissions again. It seems to have solved the problem.
