Common Causes of QuickBooks Error 15240

  • Incorrect Windows date or time
  • Firewall or internet-security software blocking QuickBooks
  • Insufficient Windows permissions
  • Damaged QuickBooks update components
  • QuickBooks File Copy Service being disabled

  • Incorrect internet/security configuration

Before making major changes, create a backup of your QuickBooks company file.

How to Fix QuickBooks Update Error 15240

1. Run QuickBooks as an Administrator

Administrative restrictions can prevent QuickBooks from accessing update files.
  1. Close QuickBooks Desktop.
  2. Right-click the QuickBooks icon.
  3. Select Run as administrator.
  4. Choose Yes when Windows asks for permission.
  5. Try downloading the QuickBooks or payroll update again.
Intuit specifically recommends running QuickBooks with administrator privileges for 15XXX update errors.

2. Check Your Computer’s Date and Time

Incorrect system time can interfere with secure connections and update verification.
  1. Open Windows Settings.
  2. Go to Time & Language > Date & Time.
  3. Make sure the date, time, and time zone are correct.
  4. Enable automatic time synchronization if appropriate.
  5. Restart QuickBooks and try the update again.
Intuit lists incorrect system date and time among the potential causes of Error 15240.

3. Check Firewall and Internet Security Settings

A firewall or security application may prevent QuickBooks from communicating with Intuit’s update servers. Make sure QuickBooks has permission to access the internet. In particular, Intuit recommends checking access for:
  • QBW32.exe
  • qbupdate.exe
Also make sure required internet ports, including 80 and 443, aren’t being blocked by your security software. If you’re using third-party firewall software, follow its documentation for adding QuickBooks to the allowed applications list.

4. Run Quick Fix My Program

The QuickBooks Tool Hub can repair certain program-related problems and stop lingering QuickBooks processes that may interfere with updates. If you regularly troubleshoot QuickBooks Desktop problems, our guide to QuickBooks Tool Hub can help you understand how the utility works and which troubleshooting tools are available. To run Quick Fix:
  1. Close QuickBooks Desktop.
  2. Open QuickBooks Tool Hub.
  3. Select Program Problems.
  4. Choose Quick Fix my Program.
  5. Wait for the process to finish.
  6. Open QuickBooks again.
  7. Download the update.
Intuit recommends Quick Fix my Program as one of the solutions for 15XXX update errors.

5. Reset the QuickBooks Update

If the downloaded update components are damaged, resetting the update can force QuickBooks to obtain fresh files.
  1. Open QuickBooks Desktop.
  2. Select Help > Update QuickBooks Desktop.
  3. Choose Update Now.
  4. Select Reset Update.
  5. Click Get Updates.
  6. Once the download finishes, close and reopen QuickBooks.
  7. Run the update again.
Intuit also recommends deleting the relevant QuickBooks Components folder in certain 15XXX-error situations before resetting and downloading the update again. This should be done carefully and according to the installed QuickBooks version.

6. Check Windows Permissions

If QuickBooks doesn’t have sufficient access to its installation directories, update files may fail to open or install. Intuit recommends reviewing permissions for relevant Intuit folders, including locations under:
  • C:\Program Files\Intuit
  • C:\ProgramData\Intuit
  • C:\Program Files\Common Files\Intuit
The exact folder structure depends on your Windows installation and QuickBooks version. If you’re uncomfortable changing Windows ownership or permissions, avoid making advanced permission changes without professional guidance.

7. Check the QuickBooks Digital Signature

A problem verifying the QuickBooks executable’s digital signature can also prevent updates. Intuit’s troubleshooting procedure involves locating QBW32.exe, opening its Properties, selecting Digital Signatures, and checking the Intuit certificate. If necessary, the certificate can be installed through Windows’ certificate wizard. Restart Windows afterward and try the update again.

8. Repair QuickBooks Desktop

If the previous solutions don’t work, the QuickBooks installation itself may have damaged components. The QuickBooks Install Diagnostic Tool can help repair common installation-related problems. Intuit recommends repairing QuickBooks as another troubleshooting option for 15XXX update errors. If repairing doesn’t resolve the issue, reinstalling QuickBooks Desktop may be necessary.

  • Keeping QuickBooks Desktop updated.
