This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, search for article #322756 in the Microsoft Knowledge Base.
Follow these steps:
(1) Log on to the computer by using an Administrator user account.
(2) Click Start, click Run, type regedit, and then click OK.
(3) In Windows Vista you may receive a User Account Control (UAC) dialog box. You must click Continue to open Registry Editor.
Locate and then right-click the following registry subkey as appropriate.
On 32-bit versions of Windows:
For Microsoft Office 2003: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\11.0
On 64-bit versions of Windows:
For Microsoft Office 2003: HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Office\11.0
(4) Click Permissions.
(5) Click Users (Computer_name\Users), and then click to select the Allow check box for the Full Control permission.
(6) Click OK, and then quit Registry Editor.
(7) Start an Office program, and then accept the End User License Agreement.
(8) Repeat steps 2 through 4, and then remove the Full Control permission that you gave to Users (Computer_name\Users) in step 5. To do this, locate Users (Computer_name\Users), and then click to clear the Allow check box for the Full Control permission.
(9) Click OK, and then exit Registry Editor.
I hope this helps...
