Hi, depending on the version/edition of Office you have, you may be able to extend the trial period a little more.
To rearm your Office 2010 installation
Make sure all Office 2010 applications are closed.
Open an elevated command prompt.
Go to %installdir%\%Program Files%\Common Files\Microsoft Shared\OfficeSoftwareProtectionPlatform. If you installed the 32-bit edition of Office 2010 on a 64-bit operating system, %Program Files% is the Program Files (x86) folder.
