In this guide, we’ll explain what Error 15106 means, what causes it, and how to troubleshoot it step by step.

What Is QuickBooks Error 15106?

QuickBooks Error 15106 is a QuickBooks Desktop update error. It usually appears when QuickBooks is attempting to download or install an update but cannot access or run the required update program.

According to Intuit, users may encounter one of two messages:

• Error 15106: The update program cannot be opened
• Error 15106: The update program is damaged

Intuit identifies antivirus software blocking the QuickBooks update and insufficient Windows administrator privileges as key causes of the error. 

Error 15106 can occur when updating QuickBooks Desktop or downloading the latest payroll tax table.

What Causes QuickBooks Error 15106?

There isn’t always a single cause of Error 15106. Several Windows, security, and QuickBooks update components can contribute to the problem.

1. Antivirus Software Is Blocking QuickBooks

Security software may identify a QuickBooks update component as suspicious and prevent it from running.

When this happens, QuickBooks may display Error 15106 because it cannot access the update program.

Intuit specifically lists antivirus interference as one of the primary reasons for Error 15106. 

2. You Are Not Signed In as a Windows Administrator

QuickBooks may need elevated Windows permissions to install program updates.

If the current Windows account doesn’t have administrator privileges, QuickBooks may be unable to modify the files required for the update.

3. Damaged QuickBooks Update Components

QuickBooks stores update-related files and components on the computer. If one of these components becomes damaged, QuickBooks may not be able to complete the update.

A damaged downloadqbXX folder can be particularly relevant to Error 15106.

4. QuickBooks File Copy Service Is Disabled

QuickBooks uses the QuickBooks File Copy Service (FCS) during certain update processes.

Intuit’s broader 15XXX troubleshooting guidance identifies a disabled QuickBooks File Copy Service as one possible cause of update errors in this group, which includes Error 15106. 

5. Firewall or Internet Security Restrictions

Firewall and internet-security settings can interfere with QuickBooks updates.

If QuickBooks cannot establish the necessary connection or access the files required for an update, an update error may appear.

6. Digital Signature Verification Problems

QuickBooks program files use digital signatures to help verify their authenticity.

Intuit includes inability to verify digital signatures among the possible causes of QuickBooks 15XXX update errors, including Error 15106. 

Symptoms of QuickBooks Error 15106

You may be experiencing Error 15106 if:

• QuickBooks Desktop won’t update.
• A payroll tax table update fails.
• QuickBooks displays “The update program cannot be opened.”
• QuickBooks says “The update program is damaged.”
• The update stops before completion.
• QuickBooks repeatedly asks you to install an update.
• An update fails even though your internet connection is working.
• Error 15106 appears when downloading QuickBooks updates.

How to Fix QuickBooks Error 15106

Try the following solutions in order. Start with administrator access because it is one of Intuit’s recommended first steps.

Solution 1: Run QuickBooks as an Administrator

The simplest solution is to give QuickBooks the Windows permissions it needs to perform the update.

1. Close QuickBooks Desktop.
2. Right-click the QuickBooks Desktop icon.
3. Select Run as administrator.
4. Select Yes if Windows asks for permission.
5. Open the QuickBooks update window.
6. Try downloading the update again.

Intuit currently recommends downloading QuickBooks updates as an administrator as the first troubleshooting step for Error 15106. 

If the update succeeds, you don’t need to continue with the remaining steps.

Solution 2: Check Your Antivirus Software

If running QuickBooks as an administrator doesn’t fix the problem, antivirus software may be interfering with the update.

Intuit recommends checking the antivirus application if Error 15106 continues. In its specific Error 15106 instructions, Intuit advises stopping the antivirus process and then attempting the update again. 

Because antivirus software protects your computer, don’t leave it disabled unnecessarily.

If you’re unsure how to safely pause or configure your security software, consult the security vendor’s documentation or your IT administrator.

Once you’ve finished testing, make sure your security protection is enabled again.

Solution 3: Rename the QuickBooks Download Folder

A damaged QuickBooks update folder can prevent the update program from running.

Intuit’s current Error 15106 instructions recommend renaming the downloadqbXX folder.

Follow these steps:

1. Close QuickBooks Desktop.
2. Open File Explorer.
3. Navigate to:

C:\Program Files\Intuit\QuickBooks(year)\Components

For 64-bit Windows installations, Intuit specifies:

C:\Program Files (x86)\Intuit\QuickBooks(year)\Components

4. Locate the downloadqbXX folder.
5. Right-click the folder.
6. Select Rename.
7. Add .old to the end of the folder name.

For example:

downloadqbXX.old

8. Open QuickBooks Desktop.
9. Try downloading the update again.

The exact XX corresponds to your QuickBooks Desktop version. 

Solution 4: Run Quick Fix My Program

The QuickBooks Tool Hub contains tools designed to resolve common QuickBooks Desktop problems.

Intuit’s current 15XXX troubleshooting instructions recommend running Quick Fix my Program through QuickBooks Tool Hub. 

To use it:

1. Close QuickBooks Desktop.
2. Open QuickBooks Tool Hub.
3. Select Program Problems.
4. Select Quick Fix my Program.
5. Wait for the process to finish.
6. Reopen QuickBooks.
7. Try downloading the update again.

Quick Fix my Program shuts down lingering QuickBooks background processes and performs a quick repair of the program.

Solution 5: Reset the QuickBooks Update

If the Quick Fix doesn’t resolve the problem, reset the QuickBooks update.

Intuit’s current troubleshooting instructions recommend deleting the Components folder and then resetting the update from inside QuickBooks. 

First, close QuickBooks Desktop.

Navigate to:

C:\ProgramData\Intuit\QuickBooks XX\Components

The exact version number varies according to your QuickBooks Desktop installation.

Then:

1. Delete the Components folder.
2. Open QuickBooks Desktop.
3. Select Help.
4. Select Update QuickBooks Desktop.
5. Select Update Now.
6. Select the Reset Update checkbox.
7. Select Get Updates.
8. Wait for the download to finish.
9. Close and reopen QuickBooks.
10. Return to Help > Update QuickBooks Desktop.
11. Select Overview.
12. Select Update Now.

This forces QuickBooks to rebuild its update components and download the update again. 

Solution 6: Check the QuickBooks File Copy Service

If Error 15106 continues, check whether the QuickBooks File Copy Service is enabled.

Intuit lists a disabled QuickBooks File Copy Service (FCS) as one of the possible causes of 15XXX update errors. 

To check Windows services:

1. Press Windows + R.
2. Type:

services.msc

3. Press Enter.
4. Look for the QuickBooks File Copy Service associated with your QuickBooks version.
5. Check its status.
6. If appropriate, make sure the service is enabled and running.
7. Reopen QuickBooks and try the update again.

If you are unsure which QuickBooks service belongs to your installation, avoid changing unrelated Windows services.

Solution 7: Check the Digital Signature

QuickBooks update errors can sometimes be associated with problems verifying digital signatures.

Intuit’s current 15XXX guidance provides the following method for checking the QuickBooks executable:

1. Navigate to:

C:\Program Files\Intuit\QuickBooks

2. Locate QBW32.exe.
3. Right-click it.
4. Select Properties.
5. Open the Digital Signatures tab.
6. Verify that Intuit appears in the signature list.
7. Select Details.
8. Select View Certificate.
9. Select Install Certificate.
10. Follow the installation wizard until the certificate is installed.
11. Restart the computer.
12. Open QuickBooks.
13. Try downloading the update again.

Intuit includes digital-signature verification as a troubleshooting step for QuickBooks 15XXX update errors. 

Solution 8: Repair QuickBooks Desktop

If the update still fails, the QuickBooks installation itself may need repair.

Intuit recommends using the QuickBooks Install Diagnostic Tool to repair common installation problems. 

You can access the tool through QuickBooks Tool Hub.

Generally:

1. Close QuickBooks.
2. Open QuickBooks Tool Hub.
3. Select Installation Issues.
4. Run the appropriate installation diagnostic tool.
5. Restart the computer after the repair.
6. Open QuickBooks.
7. Try the update again.

Solution 9: Reinstall QuickBooks Desktop

If none of the previous solutions work, reinstalling QuickBooks Desktop may be necessary.

Intuit includes reinstalling QuickBooks among its troubleshooting options for 15XXX update errors. 

Before reinstalling:

• Create a backup of your company files.
• Keep your QuickBooks license and product information available.
• Close QuickBooks.
• Make sure you have Windows administrator access.
• Use Intuit’s recommended installation or clean-install procedure.

A reinstall replaces damaged or missing program components that may be preventing QuickBooks from updating.
