Need to Upgrade to 4.5.10 from 2.0 but I don't have access to the books anymore

Hi there,

I have been running ADE on a windows 7 computer and need to upgrade to Windows 10 because windows 7 is being de-commissioned next year.  I currently have about .  So am looking to Upgrade ADE to 4.5.10 from 2.0 but I don't have access to the books anymore (only in my ADE 2.0).

Can anyone give me advice on how I could keep my books?

Would really appreciate

Thank you
