Permission from Windoze (who is asleep at the switches). We have been seeing lots of this type of error. Windows forgets that your userid has update access rights to various files, folders and registry entries.  Try using this tip to fix it:
Solving setup errors by using the SubInACL tool to repair file and registry permissions - If that doesn't work, try running the setup file as admin
Win 7 5 ways to Run As Admin - 5 ways to run as admin

In Windows 7, even when you are logged in as administrator, UAC no longer gives you “Full” administrator rights. To get all of the access you now also have “run as administrator”

It appears there is an error where your userid is not being allowed to update the activation information.

What you need to do is "runas admin":

  • Go to the start menu and find the program icon you want to start
  • <Shift> <Right Click> on it
  • Select “Run as …”

If that doesn’t work try this:

  • In the start menu, right click on the shortcut for any Office app, select “RunAs Admin”
    If runas does not appear, right click and drag the shortcut to the desktop
  • create a shortcut on the desktop.
  • Right click on the desktop shortcut,
  •  runas admin should be there.

Activate the application/office:

  • 2007 Office button / 2010 File tab
  • Help
  • Click on “Activate the Application”
  • Follow prompts to enter product key
  • Close the app
  • Restart app normally

Why “Run As Admin” when logged in as Admin -


What is 'Run as Administrator' in Windows 7?


If that doesn’t work, try rebooting into Safe mode (with networking) to do the install/activation.

Start Win7 in safe mode  - - Please let us know if works or not.
