Hello, Maddycar1.
I appreciate doing what you can do move your company file. I'll share a guide to help you resolve the error when transferring to a new computer.
You can get around the error by manually downloading the QuickBooks Installer. Simply go to the new computer and download the installer from here: https://downloads.quickbooks.com/app/qbdt/product.
After downloading, simply open the installer and install QuickBooks normally. This article might prove useful to you if you need help: Install QuickBooks Desktop.
Finally, move your company file after setting up your Desktop program.
If you're ready to work on the new computer, you can check out our guides on how to manage your business in QuickBooks. Start by browsing a topic from the general support page. Then, look for an article of your choice.
I'd be more than happy to lend a hand again if you need help in QuickBooks Desktop. Add as much as details as you can to your reply and I'll get back to you as soon as possible.
