How to Fix QuickBooks Error 15240
If you encounter QuickBooks Error 15240, you should handle it sequentially. First, resolve the small problems and move on to handling the bigger ones if required.
Solution 1: Run QuickBooks as Administrator
Providing administrator access to QuickBooks allows it to update itself.
- Close QuickBooks Desktop.
- The QuickBooks icon will be available on your computer, be it on the desktop or the Start Menu.
- Once you find the icon, right-click it and then pick “Run as administrator.”
- Make another effort to download the update.
Solution 2: Ensure the System Date and Time is Set Correctly.
An incorrectly set date and time may lead to security problems on your device.
- Close QuickBooks Desktop.
- Accessorize your device by opening the Settings app; press Windows key R along with I at the same time.
- Go to “Time & Language.”
- Now, double-check that the date and time are correct.
- If Set time automatically is activated, make sure the time zone is also updated. Change it yourself if it is not correct.
- Press the “Sync now” button available in the “Additional settings” area.
- Try updating QuickBooks after restarting your computer.
Solution 3: Assign Windows Permissions to the QuickBooks Installation Directories.
The updates may fail for a user should there not be full access to the computer where QuickBooks is installed. All parts of the computer to be used must be accessible to the user.
- Identify QuickBooks Installation Folders: Normally default installation paths are:
- C:\Program Files\Intuit\QuickBooks [Year]
C:\ProgramData\Intuit\QuickBooks [Year] ***Background Note: Users seldom see program data.
C:\Users\Public\Documents\Intuit\QuickBooks [Year]
- C:\Program Files\Intuit\QuickBooks [Year]
- Modify Folder Permissions
- Right-click the QuickBooks installation folder and choose Properties.
- Go to the “Security” tab.
- Click “Edit.”
- When you get to the “Permissions for [Folder Name]” screen, click on “Add.”
- Type the name of your Windows user account into the box and press “Check Names” after. Once found, click “OK.”
- Click on the user account you wish to use in the “Group or user names” list.
- In that section for your user name, click the “Full control” checkbox in the “Allow” section.
- Choose “Apply” from the menu, and then “OK” on all the open windows.
- Follow these procedures for each QuickBooks installation folder.
- Shutdown your computer, then try to update QuickBooks again once it restarts.
Solution 4: Verify the Internet Explorer Settings
If you use another browser besides Internet Explorer, QuickBooks can still rely on those browser parts to update.
- Open Internet Explorer.
- From the top-right corner, find the gear icon and click it. Select “Internet Options” from the drop-down list.
- Go to the “Security” tab.
- Go to “Trusted Sites” and hit the “Sites” button there.
- Add the below Intuit websites if you do not already have them set up:
- *.intuit.com
- *.quickbooks.com
- *.payroll.com
- *.intuitcdn.net
- Close the “Trusted sites” window.
- Go to the Security tab and set Trusted Sites to a security level of Medium or lower.
- Go to the “Advanced” tab.
- Check the following options under the “Security” heading:
- “Use TLS 1.0”
- “Use TLS 1.1”
- “Use TLS 1.2”
- Turn down: “Check for publisher’s certificate revocation” coupled with “Check for server certificate revocation”.
- Click “Apply” and then “OK.”
- Shutdown your computer, then try to update QuickBooks again once it restarts.
Solution 5: Check your Third-Party Firewall
It is possible that your firewall is preventing QuickBooks from connecting to the correct servers.
- Temporarily disable your third-party firewall. (Important: Use it just for a short period to figure out the problem. Remember to re-enable it afterward.)
- Follow the steps to install the QuickBooks update.
- Once the update is done, you have to change your firewall settings to make sure QuickBooks can run properly. Use the instructions found in your firewall’s documentation to allow specific programs and ports. The default location for these files is within the QuickBooks installation folder (in my case, C:\Program Files\Intuit\QuickBooks [Year]). Please consider granting permission for QBUpdate.exe and QBW32.exe.
- Once configured, re-enable your firewall.
Solution 6: Upgrade to the Newest QuickBooks Version Yourself.
If automatic updates are not working, you may try to update the software manually.
- Go directly to the Intuit QuickBooks official support page.
- Click on “Update” in QuickBooks, or visit downloads section.
- Pick the edition of QuickBooks Desktop you have, and then download the latest available update.
- QB should be closed.
- Installation of the downloaded file should be done by double-clicking on it. Follow the steps provided on the screen.
- After completing the manual update, open QuickBooks to see if the payroll update can now be downloaded again.
Solution 7: Try Fixing QuickBooks Desktop Using Tool Hub.
QuickBooks Tool Hub is offered by Intuit to help users solve a range of problems, with updating being just one of them.
- Get the QuickBooks Tool Hub and install it onto your computer.
If you don’t have QuickBooks Tool Hub yet, you can download it from the official Intuit website. Just follow the installation instructions.
- Run QuickBooks Tool Hub
Click the icon to open QuickBooks Tool Hub.
- Choose “Program Problems.”
Click on the “Program Problems” menu.
- Run “Quick Fix my Program”
Click on the “Quick Fix my Program” button and let the process finish. Just a few minutes, that’s all it will take from you.
- Restart QuickBooks
Once you’re done with the quick fix, launch QuickBooks and run the update once again.
Solution 8: Check Windows Firewall and Security Software
Sometimes, updates for QuickBooks do not work because the in-built Windows Firewall or installed security solutions are blocking them.
- Check Windows Firewall Settings
- Type “Windows Defender Firewall” in the Windows search bar to access it.
- The next step is to click on “Allow an app or feature through the Windows Firewall.”
- To access the settings, click on “Change settings” with your administrator privileges.
- Make sure that the list includes any needed QuickBooks lines. All QuickBooks programs, such as QBUpdate.exe and QBW32.exe, should have their “Private” and “Public” checkboxes selected. If you didn’t find the apps you need, click on “Allow another app…,” pick C:\Program Files\Intuit\QuickBooks [Year] as the installation folder, highlight the executable files, and hit “Open” and then “Add.”
- Disable Windows Security on the Gaming Machine (if the circumstances call for it)
- Start by typing “Windows Security” in the Windows search bar and clicking on it.
- Open the “Virus & threat protection” section and click on “Manage settings” next to it.
- Temporarily turn off “Real-time protection.” Don’t forget to turn on your TV after you’re done troubleshooting.
- Attempt the QuickBooks update. If your attempt to log in be successful, you may need to allow QuickBooks as an exception in your Windows Security settings.
Solution 9: Allow Permissions for Location of Download Files
Check folder settings granting access to location path where QuickBooks saves update files.
- Find the download location.
Normally, it tends to save the file either in your user profile or in the QuickBooks software installation folder. However, it differs depending on the location.
- Check Permission
Search in File Explorer for the place you suspect the malware got downloaded. To access the “Security” tab, right-click on the folder and select “Properties”. Make sure that your user account is allowed both “Read” and “Write” permissions there. If this does not work, proceed to Solution 3 to fix the permissions.
Note: If the steps mentioned above do not work, the next step is to reach out to QuickBooks support for help. With their training and resources, they can tackle more difficult update issues.
