Cannot add a license for SU 2016

Can anyone help me on this? This is for SU 2016.

Hi all,

Requesting your assistance for our Sketch Up 2016 license error, it was successfully installed in our unit but failed to activate the license.

I already tried to use personal internet connection but when we tried to click the ADD LICENSE button, no output or error showed in the screen.

Looking forward to any feedback/recommendation for this concern.

Thank you so much

Please don’t double post.
