QuickBooks software is popular among business owners, largely because it's versatile and can be tailored to suit the needs of virtually any type of business. It is easy to operate and manage and offers a step-by-step setup guide, as well as countless tutorials. As with most software programs, QuickBooks does require an installation; should you need to, you can reinstall the program even if you don’t have your original QuickBooks CD. By following a few simple steps, you can be up and running again in about 20 minutes.

Gather License and Product Numbers

If you no longer have the CD that came with your QuickBooks software, you can still perform a reinstall on your computer. You will need the original license and product numbers, as well as a download of the installation files that correspond to your particular version of QuickBooks. If you do not have your license and product numbers, you can visit the QuickBooks License and Key Code Lookup page to access them.

Download Installation Files

You will need to download the QuickBooks installation files, which are available in the My Downloads section. Use your login information and the license and product numbers from your original purchase to download the files. Complete the installation process as per the instructions and prompts you are given.


You will not be required to register QuickBooks after you reinstall it if you are placing it on the same computer. However, if you choose to reinstall it on a different computer, you will be prompted to register it again. Click on "Register QuickBooks" on the "Help" menu and enter your business information. Once your information is recognized by QuickBooks, it will automatically complete the registration process for you and you will be up and running.
