QuickBooks Desktop 2020 — Download, Install, Activation & Get Started

Complete Guide for QuickBooks Pro 2020, Premier 2020 & Enterprise 20.0

QuickBooks Desktop 2020 holds a special place for a lot of small business owners. It was the last year Intuit sold Pro and Premier as a one-time purchase — no subscription, no annual renewal, just buy it and own it. (We wrote about this in depth in our post on buying QuickBooks Desktop without a subscription.) Starting with the 2021 versions, Intuit switched Pro and Premier to mandatory subscriptions (Pro Plus and Premier Plus). So if you already have a 2020 license, you're sitting on the last of a kind.

Whether you're reinstalling on a new computer, setting up a second machine, or getting it loaded for the first time — this page covers everything you need to download, install, and activate QuickBooks Desktop 2020. All three versions follow the same process, so we've kept it in one place.

What Is QuickBooks Desktop 2020?

QuickBooks Desktop 2020 is Intuit's desktop accounting software from the 2020 release year. It runs on your Windows computer — not in a browser — and handles invoicing, expense tracking, reports, inventory, bill management, and everything else you need to keep your books straight.

This was a hugely popular version because it was the final year you could buy QuickBooks Pro and Premier outright without a subscription. A lot of businesses stocked up on 2020 licenses for exactly that reason. The software still works great for offline bookkeeping — it just won't connect to bank feeds, payroll services, or receive security updates anymore.

What Was New in 2020?

• Improved payment processing — Faster, more reliable payment handling for customer invoices and online payments.
• Automated statement charges — Set up recurring statement charges so you're not entering the same thing every month by hand.
• Enhanced search — Better search across transactions, customers, and vendors. Finds what you're looking for faster.
• Better check printing — Improved formatting and alignment when printing checks, fewer paper jams and reprints.
• Collapse and expand columns in reports — Click to collapse or expand report columns so you can focus on the data that matters without scrolling through everything.

After You Purchase — What You'll Receive

QuickBooks Desktop 2020 — Download, Install, Activation & Get Started

Installation — Step by Step

Same process for Pro, Premier, and Enterprise 20.0. Takes about 10-15 minutes.

How to Activate

Activation confirms your license is genuine. You have 30 days after install to activate.

Phone activation backup: If online doesn't work, go to Help → Activate → choose "activate by phone." Call the number shown, give them your validation code, and enter the confirmation code they give you. Phone activation is often the most reliable method for older versions like 2020.

Troubleshooting — Common Issues

Download Stops or Fails

Delete the partial file, check your internet, and try again. Switch browsers if it keeps failing.

Installation Fails or Crashes

Turn off antivirus, check disk space (need 2.5 GB free), restart your computer, and run the installer as Administrator (right-click → Run as administrator).

Error 1903 or 1904

Run Windows Update, install everything available, restart, and try again. If it persists, install Microsoft .NET Framework from Microsoft's website.

Error 3371 — Can't Load License Data

Close QuickBooks. Go to C:\ProgramData\Intuit\Entitlement Client\v8 and delete EntitlementDataStore.ecml. Reopen QuickBooks and re-enter your key.

QuickBooks Crashes on Open

Uninstall from Settings → Apps, restart, turn off antivirus, reinstall as Administrator, restart again.

"License Already In Use"

Uninstall from the old computer first. If you can't, call us and we'll help. Phone activation sometimes resolves this automatically.

Firewall or Antivirus Blocking QuickBooks

Add QuickBooks as a trusted app in your antivirus. In Windows Firewall: Control Panel → Allow an app through firewall → check QuickBooks for both Private and Public.

Activation Takes Longer Than Expected

This is normal for older versions. Intuit's activation servers still work for 2020, but they can be slower since the product is discontinued. Try once or twice online, and if it's not cooperating, use phone activation instead. That almost always works on the first try.

Should You Upgrade?

Let's be straight with you. If QuickBooks 2020 still does what you need, there's no reason to panic. Plenty of businesses run it every day for basic bookkeeping — entering transactions, printing checks, running reports, managing invoices. For that kind of work, it's still solid.

But here's where it falls short now that support has ended:

• No bank feeds — You can't automatically download transactions from your bank. Everything has to be entered manually or imported from CSV files.
• No payroll updates — Tax tables aren't updated, so running payroll through QuickBooks 2020 means incorrect withholdings. You'll need a third-party payroll service.
• No security patches — Any vulnerabilities discovered after the cutoff date won't be fixed. If your computer stores sensitive financial data, that's a real concern.
• No online backup — Intuit's cloud backup no longer works with 2020. Back up your files manually to an external drive or other cloud service.

If any of those are deal-breakers for you — especially bank feeds or payroll — it's honestly worth looking at a newer version. QuickBooks Desktop 2024 or 2025 will give you all of that back, plus better performance and full Windows 11 support.
