For all the folks out there still running Windows XP, you will be in for a surprise when you go to upgrade Quickbooks. Starting with Quickbooks 2015, you can not install it on Windows XP. I haven’t tried all the possible workarounds yet, but the installer will check to see if you are running Windows XP and will prevent you from continuing. You can also see the list of requirements for Quickbooks 2015 here.
If I discover a workaround, I will post it. However, I highly recommend that you upgrade to Windows 7 or later. It’s way past time for you to upgrade. 😉
