Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Hải
Gmetrix requires that a compatible Microsoft Office PrimeryInterop assembly is installed for the version of Microsoft Office you are using, those can be downloaded and installed from the Gmetrix website
There are a lot of posts on the Gmetrix forums about this and they mainly say you need to match the version of Gmetrix to your Office version . . .
The best option is to contact Gmetrix and ask them where to download that from . . .
