I have a legitimate copy of Office 2003 which has been installed and working fine on my computer.  However, last Wednesday my computer crashed and I had to reinstall Windows Vista and all my programs, including Office 2003.  When I installed Office 2003, it validated ok, but now every time I open an Office program or a file in one of the programs, I am asked to "Accept" the EULA.  When I click on the dialog, it goes away and I can use the program.  But, the next time I open an Office program it starts all over again.  How can I fix this?

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.

• give the account that you are using administrative rights
• run office and accept the eula
• check you no longer have to accept eula
• remove admin rights

Solution 3

I too had this problem and have been scouring for an answer.  Everyone says sign on with and administrator account, but I already am.  Finally I went to Control Panel-User Accounts and turned User Account Control Off.  Rebooted machine, started office programs, accepted EULA's, restarted office programs to make sure EULA doesn't pop up, go back to User Accounts and turn User Account Control on, rebooted. Now EULA doesn't pop up anymore.
