While, browsing TechyV for solutions, I found your question and somehow I felt like I want to help since i had this kind of problem in the past as well.

I will include here some steps you can try on your own as these steps are what i did to resolve my issue. Please care to try.

As i looked this up, this error suggests that the product key installed is not correct or is not being accepted on your system. Either the registry for accepting the product key is corrupt or does not match the version or Office you have which may have happened after an update.

Alright, let’s get to this.

1) First I would suggest you first check all the versions of Microsoft Office currently installed on your computer via

A) Going to your  installed programs list.

B) Copy and paste this link to download MGADiags then install and run it.

to check the currently installed Product Key you have in the Office Tab.

Sample Microsoft Genuine Advantage Diagnostic

C) Download and Install Speccy which can check most of the installed programs and their corresponding product keys and remove older versions. Get if from filehippo.

Ideally, you would have to remove older versions of Microsoft Office that are currently installed on your computer. Remove also Microsoft Office versions that does not match your Product Key.

Contact Microsoft to check the validity of your Product Key and Assistance if the Microsoft Office 2010 installed on your computer may need to be cleaned and reinstalled if there is a chance of corrupt program or registry.

This error is usually due to a problem in the Microsoft licensing store which needs to be recreated. These steps will rebuild the store files:
1. Click start then type "%windir%system32".
2. Look for the "cmd.exe" file, right-click it then select "Run as administrator".
3. On the command prompt encode "net stop slsvc" then press Enter. It will ask for confirmation then select yes.
4. After that, encode the following in the right sequence:
cd %windir%ServiceProfilesNetworkServiceAppDataRoamingMicrosoftSoftwareLicensing
rename tokens.dat
cd %windir%system32
net start slsvc
cscript slmgr.vbs -rilc (This particular command may take some time but patience is a virtue.)
5. After finished, restart your computer.
Try to re-enter the original product key and the error should be gone.
