You're in the right place to find out what you need to know about installing, registering, and setting up a network. Here you'll learn about how to install your version, how to register and set up a network, and how to troubleshoot installation problems.

When you install a new version of QuickBooks on a computer where another version is already installed, you have the choice of adding the new version or upgrading and replacing the earlier version.

• Upgrade and replace an earlier version. This is a good choice for users who don't use more than one version of QuickBooks on the same computer.

  We recommend that you back up your company file before upgrading your version of QuickBooks.

• Add the new version to your computer, keeping earlier versions available as well. This is a good choice for users who need to switch between different versions, such as ProAdvisors or accountants.
