You try to update QuickBooks® Desktop — either a software update or a payroll tax table download — and instead of a smooth update, you get QuickBooks® Error 15106. The message usually reads "The update program is damaged" or "The update program cannot be opened." The update stops, and no matter how many times you click "Get Updates," the same error appears.
QuickBooks® Error 15106 is an update-specific error that prevents QuickBooks® Desktop from downloading or installing updates. Unlike errors that affect your company file or data, Error 15106 only affects the update mechanism. Your existing QuickBooks® installation and all your financial data remain completely untouched and functional.
The update program cannot be opened. Please redownload the update.
What Causes QuickBooks® Error 15106?
Error 15106 is fundamentally a permissions and file integrity issue. When QuickBooks® tries to download an update, it needs to write files to specific folders on your computer. If anything prevents that writing process — whether it's Windows permissions, antivirus interference, or corrupted update components — Error 15106 appears.
- Insufficient Windows permissions — The Windows user account running QuickBooks® doesn't have write access to the QuickBooks® installation folder (usually in C:\Program Files). This is the #1 cause, especially on computers where User Account Control (UAC) is set to high.
- Antivirus blocking the update — Security software may identify the QuickBooks® update downloader as suspicious and block it from executing or writing files to disk. Norton, McAfee, and Kaspersky are frequent offenders.
- Damaged update components — Previous failed update attempts can leave behind corrupted files in the QuickBooks® update folder, which then block subsequent update attempts.
- Digital signature verification failure — QuickBooks® verifies the digital signature of each update file before installing it. If the signature check fails (due to a partial download or file corruption), Error 15106 appears.
- Multiple instances of QuickBooks® running — If QuickBooks® is open in multiple windows or another QuickBooks® process is running in the background, the update process can't get exclusive access to the files it needs to modify.
- Internet connection issues — An unstable internet connection can cause partial downloads, resulting in corrupted update files that trigger the error when QuickBooks® tries to install them.
6-Step Fix for QuickBooks® Error 15106
⚠️ Before you start: Close QuickBooks® on all computers that share the company file. Check Task Manager (Ctrl+Shift+Esc) to make sure no QBW32.exe or QBUpdate.exe processes are running in the background.
1 Run QuickBooks® as Administrator
This is the fastest fix and resolves Error 15106 in the majority of cases. Running as administrator gives QuickBooks® the elevated permissions it needs to write update files.
- Close QuickBooks® completely
- Find the QuickBooks® icon on your Desktop or Start menu
- Right-click on it and select "Run as administrator"
- Click "Yes" when the User Account Control prompt appears
- Once QuickBooks® opens, go to Help → Update QuickBooks Desktop
- Click "Update Now" tab → check "Reset Update" → click "Get Updates"
If the update downloads successfully this way, you can make this permanent: right-click the QuickBooks® shortcut → Properties → Compatibility tab → check "Run this program as an administrator" → Apply.
2 Fix Folder Permissions on QuickBooks® Installation Directory
If running as administrator doesn't help, the folder permissions themselves may be restrictive:
- Navigate to
C:\Program Files (x86)\Intuit\QuickBooks [Year] - Right-click the QuickBooks® folder → Properties → Security tab
- Click "Edit" to change permissions
- Select your Windows user account (or "Users" group)
- Check "Full Control" under the Allow column
- Click Apply → OK
- Try the update again
3 Temporarily Disable Antivirus
Your antivirus may be silently blocking the QuickBooks® update process:
- Right-click your antivirus icon in the system tray (bottom-right of screen)
- Select "Disable protection" or "Pause protection" for 15 minutes
- Open QuickBooks® as administrator
- Go to Help → Update QuickBooks Desktop → Update Now → Get Updates
- After the update completes, immediately re-enable your antivirus
- Add QuickBooks® to your antivirus exclusion list to prevent future blocks
4 Rename the QuickBooks® Update Folder
Corrupted files from previous failed updates can block new update attempts. Renaming the update folder forces QuickBooks® to create a fresh one:
- Close QuickBooks® completely
- Navigate to
C:\Program Files (x86)\Intuit\QuickBooks [Year] - Find the folder named "Components"
- Inside Components, find the folder named "downloadqb" (or similar update-related folder name)
- Rename it to "downloadqb.old"
- Open QuickBooks® as administrator and try the update again
QuickBooks® will create a new update folder and download fresh update files from scratch.
5 Use QuickBooks® Tool Hub
The QuickBooks® Tool Hub includes diagnostic tools that can repair update-related issues:
- Download QuickBooks® Tool Hub from the official Intuit website
- Install and open the Tool Hub
- Click "Installation Issues"
- Click "QuickBooks Install Diagnostic Tool"
- Let it run completely (15-20 minutes)
- Restart your computer
- Open QuickBooks® as administrator and try the update
6 Manually Download the Update
If the built-in updater keeps failing, you can download QuickBooks® updates directly from Intuit's website:
- Visit the official Intuit QuickBooks® Desktop downloads page
- Select your QuickBooks® edition and year
- Download the latest patch/update file
- Close QuickBooks® before running the downloaded installer
- Right-click the downloaded file → Run as administrator
- Follow the installation prompts
This bypasses the built-in update mechanism entirely and often works when the automatic updater doesn't.
Update Still Failing with Error 15106?
If these steps didn't work, the issue may involve deeper Windows permission problems or corrupted system components. Our independent technicians can diagnose and fix it remotely.
📞 Call +1-888-550-4779 — Free DiagnosisError 15106 vs Error 15270 vs Error 15215: What's Different?
All three are QuickBooks® update errors, but they point to slightly different problems. Error 15106 typically means the update program itself can't run or write files — it's a permissions or file access issue. Error 15270 usually means the update file downloaded but is corrupted or can't pass digital signature verification — it's a file integrity issue. Error 15215 often relates to Internet Explorer settings or TLS configuration that prevents QuickBooks® from connecting to Intuit's update servers.
The good news is that the fixes overlap significantly. Steps 1 through 5 above work for all three error codes. If you're specifically seeing Error 15215, also check your Internet Explorer settings: open Internet Explorer → Tools → Internet Options → Advanced → make sure TLS 1.2 is checked.
Prevention: Keeping QuickBooks® Updates Running Smoothly
Best Practices
- Always run QuickBooks® as administrator — Set this as the default in your shortcut properties to avoid permission issues.
- Add QuickBooks® to antivirus exclusions — Whitelist the entire Intuit folder (C:\Program Files (x86)\Intuit) in your antivirus settings.
- Update on a stable internet connection — Use a wired connection when possible. Don't update over mobile hotspots.
- Close all other programs during updates — Other applications competing for disk access can interfere with the update process.
- Don't interrupt updates — Once an update starts downloading, let it finish. Canceling mid-download creates the corrupted files that cause future 15106 errors.
- Keep Windows updated — Windows updates include security component updates that QuickBooks® relies on for verifying update signatures.
Frequently Asked Questions
QuickBooks Error 15106 is an update error that prevents QuickBooks Desktop from downloading or installing updates. The error typically says "The update program is damaged" or "The update program cannot be opened." It blocks software patches, security updates, and payroll tax table downloads.
Error 15106 is most commonly caused by insufficient file permissions on the QuickBooks installation folder, antivirus software blocking the update, damaged update components from previous failed attempts, or User Account Control restrictions preventing the update program from writing files.
Yes, QuickBooks itself will still function normally. However, you won't receive the latest patches, security fixes, or payroll tax table updates. Running outdated software means you may miss important bug fixes and could calculate payroll taxes incorrectly.
The most effective fix is to right-click QuickBooks and select "Run as administrator," then retry the update. If that doesn't work, temporarily disable your antivirus, check folder permissions, rename the update download folder, or use the QuickBooks Tool Hub Install Diagnostic Tool.
No. Error 15106 only affects QuickBooks Desktop editions. QuickBooks Online updates automatically through your web browser and doesn't use a local update mechanism.
Error 15106 means the update program is damaged or blocked from running — a permissions issue. Error 15270 means the update file downloaded but failed digital signature verification — a file integrity issue. The troubleshooting steps for both overlap significantly.
