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.
