[GNC] How to "move" or "recreate" my GNU 5.12 that is on Windows 10 computer over to 5.12 on Windows 11 computer

[Joseph Hymel]

Hello,I need help as the subject line states. I am not a computer tech guy and am really the accounting guy using Gnucash. I installed 5.12 on my Win 11 laptop. I then exported to CSV files from my 5.12 on Win 10 desktop the following: Account Register, Account Tree, and Account Transactions. I next exported Accounts to whatever file type it is. I assumed I could then open 5.12 on my Win 11 laptop and import same files. That did not happen as planned. 
I have years of work in my 5.12 Win 10 machine that must be able to be salvaged for the Win 11 instance of 5.12. Please help me recreate it on the Win 11 laptop. I also have numerous reports that I have created.
