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.

After a bit of digging, we discovered that a service called Bonjour was installed and running. I stopped the service, set it to disabled, and restarted the PC. This fixed the issue. It didn’t seem to affect how Extensis Portfolio operates, so I’m not sure why they are installing the service. A quick google search shows quite a few people with Bonjour network issues, so apparently it is a service used by quite a few software vendors.
