Hello there, @IT_Andy. Let's figure out, together, if it's possible to download the previous (R4) version of QuickBooks Desktop (QBDT) after updating it to the latest one.

The QBDT software is updated regularly to give you a better experience and fix issues. When you've downloaded the latest release (R5), you can no longer go back to the previous one. That's why it's impossible for us to post a download link for the previous (R4) version of QBDT.

With that being said, I would encourage you to always secure a copy or make a backup of your company file. You can pull up the one you have prior to the update so you can get back to business while our programming team works to fix the latest version of QBDT.

Also, you may want to check out this article in case you need a reference to know what's new and improved in the latest updates of QBDT 2022: Release notes for QuickBooks Desktop 2022.

Please don't hesitate to keep me posted in the comments if there's anything else you need or questions about managing your company file in QBDT. I'm always here to help. Take care, and I wish you continued success, @IT_Andy.
