New ArchiCAD 29 Serial Number doesn't work.

New Serial Number that just sent me says it is invalid on ArchiCAD 29.

Operating system used: Windows 29.3000

You should probably edit your post and blur the serial number.

I know you were trying to show us it is the same.

Have you upgraded your Archicad as was suggested?

Says I have to open my ArchiCAD project first and then return to the page.

Can you start Archicad and run in demo mode with no license?

If not you should be able to get the update from the Graphisoft website.

As far as I know there is no difference between EDU and commercial versions except for the actual license.

Yes, it should work. New serials requires latest ac29 update
