I can help install QuickBooks Desktop on your new computer, @lzimmer.
Before installing, make sure that your computer meets the minimum system requirements to run the best QuickBooks Desktop experience. Once done, go to this link: QuickBooks Desktop.
On that page, set your Country, Product, and Version. Then, click on the Download button. Once you're done, open the file that you've downloaded. Follow the prompts to finish the download.
After installing, you can now register the app. Check this article for more information: Activate QuickBooks Desktop for Windows.
From here, you can now start using your QuickBooks. See this Get QuickBooks Desktop user guides article for more information.
