Reinstall and Reactivate QuickBooks Desktop 2020 After Sunset

Learn how to reinstall QuickBooks Desktop 2020 on a new computer after its May 2023 discontinuation. Archive installers, manage activation, and insure your

QuickBooks Desktop 2020 officially reached the end of its supported lifecycle on May 31, 2023. When Intuit sunsets a version, live technical support and add-on services like payroll and bank feeds are cut off. However, the software itself remains fully capable of running offline. If you need to move your 2020 installation to a new computer or recover from a hard drive failure, you can still reinstall and reactivate the program to keep your accounting history intact.

Archive Your Essentials Right Now

Before your current hard drive fails or you migrate to a new PC, gather the necessary files. To reinstall QuickBooks 2020 independently, you need three things:

1. The Installer File: If you downloaded QuickBooks digitally, locate the QuickBooks_2020.exe setup file. If you only have installation discs, consider copying the contents to a USB flash drive or cloud storage—newer computers often lack optical drives.
2. License and Product Numbers: These are usually found in your original purchase confirmation email or on the physical CD sleeve.
3. Your Company File: Always keep a recent backup of your .qbw or .qbb file on separate media.

Store these items together in a dedicated folder so they are ready when you need them.

Reinstalling on a New PC

The installation process for QuickBooks Desktop 2020 is identical to installing any other version. Run your saved installer file, accept the license agreement, and enter your product and license numbers when prompted.

Because QuickBooks 2020 is a discontinued version, the installer may attempt to reach out to Intuit's servers to download background components or updates. To ensure a clean, offline installation that relies solely on your archived files, we recommend temporarily disconnecting your new computer from the internet while running the setup file.

Navigating the Activation Process

Getting past the activation screen is the most common hurdle when reinstalling an older, unsupported version of QuickBooks Desktop.

When you launch the software for the first time, QuickBooks will prompt you to activate. You will typically have two options:

• Online Activation: If presented with an "Activate Online" button, try this first. Even though the version is sunset, Intuit's backend servers often still validate older product codes automatically.
• Phone Activation: If the online check fails (often due to the server checks for older versions being deprecated), QuickBooks will provide an Installation Number and a phone number to call. Follow the automated telephone prompts. The system will ask for your Installation Number and provide you with a Validation Code to type into your screen.

If you encounter error codes during activation—such as validation failures or license property errors—these can sometimes stem from a damaged installation file or a corrupted Windows registry. For targeted help with stubborn QuickBooks activation errors, checking a dedicated troubleshooting knowledge base can save you a lot of trial and error.

Create Disk-Image Insurance

To avoid having to repeat the installation and activation process entirely, create a disk image of your new PC once QuickBooks 2020 is successfully installed, updated to your preferred final state, and activated.

Using tools built into Windows (like Backup and Restore) or third-party disk imaging software, take a snapshot of the operating system and applications. If your hard drive crashes in the future, you can restore this exact image to a replacement drive. The software will already be activated, completely bypassing the need to track down installers or call activation lines again.
