I downloaded and installed Office Professional Plus 2010 Key Management Service Host and when it prompted for my product key I entered the KMS volume license key that I got when purchased Office 2010 Pro. It seemed to install and activate, but I installed Office on a Win 7 client and waited a little while for it to activate. I then tried running it manually with the following command, and got the resulting error.
cscript ospp.vbs /act
Error Code: 0xC004F038
Error Description: The software licensing service reported that the computer could not be activated. The count reported by your Key Management Service (KMS) is insufficient.
I also noticed where it lists the last 5 characters of the product key don't match the product key I put in the KMS host, but it was my understanding the KMS key was pre-installed with Office 2010.
I also know we hit the minimum number for the license is for 37 copies, which I verified on Microsoft's site. Did I put the wrong key in the KMS host?
