Office 2010 activation has gone the way of Windows and now supports both MAK and KMS. This download gives you an update for KMS activation.
“An Office 2010 KMS host is required if you want to use KMS activation for your volume licensing editions of Office 2010 suites or applications, Microsoft Project 2010 or Microsoft Visio 2010. When Office 2010 volume edition client products are installed, they will automatically search for a KMS host on your organization’s DNS server for activation. All volume editions of Office 2010 client products are pre-installed with a KMS client key, so you will not need to install a product key.
This download contains an executable file that will extract and install KMS host license files. These license files are required for the KMS host service to recognize Office 2010 KMS host keys. It will also prompt you to enter your Office 2010 KMS host key and activate that key. After this is done, you may need to use the slmgr.vbs script to further configure your KMS host”.
