Hi there, @Bar2.

Thanks for reaching out to us. Let me share some info regarding the system requirement for QuickBooks Desktop (QBDT) Pro 2017.

This version only supports the following operating systems (OS):
 

• Windows 10, all editions including 64-bit, natively installed
• Windows 8.1 (Update 1), all editions, including 64-bit, natively installed
• Windows 7 SP1, all editions including 64-bit, natively installed
• Windows Server 2012 R2, Windows Server 2008 R2

If you're using Windows 11, I'd suggest using the QuickBooks Desktop 2022 or a newer version for optimal compatibility.

To find out what your computer needs for the best experience in QuickBooks Desktop 2022, you can check out this article: System Requirements for QBDT 2022. Please take note that this resource is intended for US versions of the said product. Although, the same information can still be applied to the QBDT UK versions.

Remember, you're always welcome to return whenever you need assistance in keeping your QuickBooks up-to-date. It would be my pleasure to be of assistance. Have a great day!
