I appreciate all the things you've done so far, Beryl. You have already invested significant time migrating your file to the new computer. Let's ensure you can install your QuickBooks on the latest one.

If you're using Windows 11, the best way to transfer your QuickBooks data or files is to install them manually on the other computer.

It's a good start that you have your license and product key. Now, we can proceed with downloading the installer by following these steps:

1. From the Downloads & Updates page, select your country, product, and version.
2. Click Search, then hit Download.
    

Please know that to install your product on a different computer, you will need to register it first. Here's how you can do that:

1. Head to the Help and select Register QuickBooks to start the process.
2. Once you input your information, Intuit will check the registration status of your QuickBooks copy and record the details for the other computer.

If you're using Windows 10, please check pending system updates before using the migration tool. This process helps prevent compatibility issues. 

Moreover, check out this reference for the limitations and reminders regarding transferring data between different locations, systems, or computers: Company file compatibility with QuickBooks Desktop.
