2019 sketch up perpetual licence

Hello, I purchased a perpetual licence in 2019. I havent used sketch up for some time and have since purchased a new laptop. I have the serial and authentication code but when I try to log in it says invalid. I cant find an exact download for 2019.
I do not have the old laptop to log out of any account or find exactly what version it is using.

You will probably have access to version 2020, as well.
Check the license manager:

You might try what @MikeWayzovski suggested but you can get SketchUp 2019 here.

Be aware that the 3D Warehouse no longer supports SketchUp 2019. Might be time to consider upgrading if you use the 3D Warehouse.
