You’re getting ready to install the latest version of QuickBooks, but you’ve got a prior version already installed. Can you have multiple versions installed on one computer at a time? Is this going to cause QuickBooks problems?

And if you can have multiple versions installed, should you?

First, let’s define the term ‘version’. A version in QuickBooks means a particular year’s release of one of the desktop editions of QuickBooks: Pro, Premier, Accountant, or Enterprise. So for example, QuickBooks Pro 2018 and QuickBooks Pro 2019…those are two different versions, same edition.

In most cases, YES, you can have multiple versions of QuickBooks installed on the same computer at the same time. In fact, you can has as many as your hard drive has room for. See caveats below, however.

On my own main work computer, I have all versions of QuickBooks Accountant (Premier) and QuickBooks Enterprise between 2012 and 2019 (the latest version as of this writing). No problem.

The only exceptions to this are…

  • Pro AND Premier. You can only have one or the other installed for a particular version (year).
  • US AND Canada (or other countries’ combinations). You can’t have multiple ‘region’ versions installed on the same computer.

So SHOULD you have multiple versions installed on your computer? It makes sense if…

  • You are a CPA, bookkeeper, or consultant who needs to support the files of clients who use different versions
  • You want to keep an older version (or versions) installed just in case you need to restore an old data backup associated with that old version. Of course, it should work fine to restore an old backup into a new version of QuickBooks — it should upgrade it as it restores it. But sometimes there are glitches there, and you need to restore it in the original version.

Otherwise, you can choose to uninstall the old version(s). In fact, when you install new versions, it will ask you if you want to uninstall an old version.

NOTE: Before you uninstall a version of QuickBooks, make sure that you file away the old version’s install CD (or download file if you bought it that way), your install codes, and your registration information. Just in case you need to reinstall it later for some reason.

  1. I was thinking that we can just install one version of QuickBooks like a pro, premier or Enterprise. I am using QuickBooks Enterprise and last month, I have tried to install Pro also but the system has uninstalled my Enterprise version and then have installed the Pro.

    After reading this post of Shannon, I found that May be a problem with my PC that behaves like this.

    • Hi Bookkeeper,

      Maybe it asked you if you wanted Enterprise uninstalled when you installed Pro. It sometimes does that. If you want to continue using Enterprise, you should be able to reinstall it — you can have both on your computer. Thanks for your comment.

  2. Another reason to have multiple versions installed is if you have multiple companies and like to have them open at the same time.

    I have three LLCs and one QB file for my personal. I currently use QB 2011 (for a puny LLC), 2017 for my retail LLC that links to my POS and I use 2019 for my consulting LLC and personal.

    I usually leapfrog which company gets up to the latest in order to keep them all on separate versions unless forced to upgrade for the one that uses payroll or the three that use online banking.

  3. Is it possible to change from a not-for-profit installation to a version that would support fee-for-service invoicing and job costing without having to purchase a new copy of QuickBooks? We are trying to step into our first FFS jobs but can’t afford to spend on a new copy of QB. Any thoughts or tips? Appreciate any help that is available on how to start.
