Datasmith not working

Hi.

For some reason, the datasmith installer for 3ds max 2021 does not work in my 3ds max. I ran the installer, uninstalled and installed again and nothing happens.

The installer runs and it says it is completed and installed, but when I go to File>Export in 3ds max 2021, there is no .datasmith file type to export to.

what am I missing?

Thanks in advance for your help!

Export to datasmith is now in the datasmith tab in the ribbon (for datasmith exporter 5.1 and above).
