I understand the need to be able to purchase the QuickBooks Desktop (QBDT) version you desire, Gordon. I'll share information about this.

The stand-alone version for 2024 is no longer available. With that said, you may want to upgrade to the latest version of the program (QBDT Pro Plus 2024) with support plans or purchase QuickBooks Online (QBO).

On the other hand, I recommend contacting our QBDT Sales team to ask for other alternatives you can avail. 

If you have decided to purchase one, you can read this reference to ensure you meet the minimum requirements before installing the program: What’s new in QuickBooks Desktop 2024.

Moreover, it's a best practice to regularly create a backup of your company file to ensure that you can restore the original data at any time in case of data loss or damage.

Please don't hesitate to post a reply below if you have additional concerns about QuickBooks Desktop. I'm always here ready to assist. Have a good one.
