I recognize the significance of being able to access your data in QuickBooks Desktop (QBDT), amhaas65.
Yes, you're right. QuickBooks Desktop 2023 operates on a subscription basis, which means you're unable to open the company file without a QuickBooks account.
Please note your data will remain on your device. However, if you've canceled your QuickBooks subscription and want to open or view the data again, we'll need to reactivate your subscription or purchase an outright license. With that, it would be best to restore a backup copy of your company file. We can use this article for guidance: Restore a backup of your company file.
Furthermore, Fiat Lux - ASIA is correct. You can utilize the trial version to open your data. However, the trial version we provide on our website is specifically for QuickBooks Desktop 2023. For older versions, I suggest looking outside of QuickBooks or contacting our Customer Care Team to request QuickBooks trial links and licenses for the mentioned versions.
I'm all ears if you have other concerns about managing your account. Take care!
