Hey, JoeQ. Since this Flex 5i comes with Windows 11 Home in S mode preinstalled, you may not be able to run the software. This is due to the additional security precautions in place with S mode, only allowing the device to run software that is from the Microsoft Store. Should you desire to switch to Windows 11 Home, here is a link to a Microsoft webpage that shares how to do so: (https://support.microsoft.com/en-us/windows/windows-10-and-windows-11-in-s-mode-faq-851057d6-1ee9-b9e5-c30b-93baebeebc85). Also, regarding QuickBooks, we recommend reviewing the system requirements detailed on their webpage, then comparing it with the specifications this Flex or any potential computer you’re interested in to help ensure you find the right fit for you. You can also attach a screenshot or link to a webpage with system requirements and ask for help in confirming if a system you're interested in could run the software. Hope this helps!
