This guide covers QuickBooks Desktop (Windows) in 2026, with callouts for Enterprise and Mac where the steps differ.
What Are the License Number and Product Number?
QuickBooks Desktop activation involves two identifiers:
License Number: the primary number that is associated with your purchase or subscription, and which is a symbol of your right.
Product Number: a secondary code that identifies your specific edition (Pro, Premier, Accountant, Enterprise) and is needed when activating.
They tend to appear on your Intuit email receipt, the Intuit account portal or on the original CD packaging (in older versions) or within QuickBooks itself (press F2 or Ctrl + 1) and is already turned on on another computer.
Before You Start: Confirm What You Have Installed
A Pro license will not work on a premier install. A 2024 license will not be compatible with a 2026 build. Always check your install prior to entering new numbers.
Open QuickBooks Desktop and press F2 (or Ctrl+1). The Product Information screen displays your version year, edition, current license number, product number. Always get a screenshot first then make changes.
QuickBooks License and Product Number How to change QuickBooks license and product number.
The most clean way is within the program:
- Open QuickBooks Desktop.
- Click on Help in top menu.
- Choose Manage My License.
- Click Change my License number.
- Type in your License Number and Product Number.
- Click Next and proceed with the prompts to activate.
In case you encounter a sign-in request of your Intuit account, fill in. Even with the right numbers, some of the newer licensing flows necessitate it. Once complete, close and reopen QuickBooks and then press F2 to verify the new information.
In the absence of the Manage My License option, find Help > Activate QuickBooks Desktop, Help > Register QuickBooks or Help > My License Information. The phrasing differs a bit by year and edition.
If QuickBooks Will Not Accept the New Numbers
Common reasons activation fails even with correct numbers:
- Wrong year or edition installed.
- A typo in the license, a 0 and O look almost identical.
- The license is already in use on too many machines.
- Old entitlement data is cached and overriding the new license.
- QuickBooks was not launched with Administrator rights.
Step 1: Run QuickBooks as Administrator
Close QuickBooks, right-click the icon, and select Run as administrator. Then try the license change again. Also, confirm your Windows date and time are correct; activation can fail if they are off.

Step 2: Reset the EntitlementDataStore File
QuickBooks stores activation state in a local entitlement file. If it is corrupted or tied to the old license, it will reject your new numbers. Resetting it forces QuickBooks to prompt for activation fresh. This does not affect your company file data.
- Close QuickBooks.
- Open File Explorer and navigate to: C:\ProgramData\Intuit\Entitlement Client\
- Open the subfolder inside (often named v8 or similar).
- Find the file named EntitlementDataStore.ecml.
- Rename it to EntitlementDataStore.ecml.old.
- Reopen QuickBooks as Administrator and activate with your new numbers.
If you cannot see ProgramData, go to View in File Explorer and enable Hidden items.
Step 3: Use QuickBooks Tool Hub
QuickBooks Tool Hub includes repair tools for licensing and installation issues. Download it from the official Intuit site, open it, and run Quick Fix my Program or the relevant activation repair option. Then retry the license change.
Conclusion
When you need to change QuickBooks license and product number, start inside the program: Help > Manage My License > Change My License Number. If it fails with correct numbers, reset the EntitlementDataStore.ecml file, reopen QuickBooks as Administrator, and activate fresh.
If you are still stuck, the issue is usually a mismatched edition or a license that has hit its install limit. It is best to reach out at +1.833.802.0002 to avoid raising any further errors and effectively address the issue at hand.
