Hello JTekone, thanks for posting and welcome to the Community
Please note that as of the discontinuation of QuickBooks Desktop for UK customers in June 2023, we no longer sell or offer support for Desktop software in this region.
Depending on the version of Desktop that you're using, you may be able to open the file using a trial version. You can click here to download, install and use the 30 day version of QuickBooks Desktop 2021.
If you'd like further information on the discontinuation, please see here.
