How to Fix QuickBooks Error Code 15103?

After you’ve identified the source of the issue, the next step is to implement the troubleshooting techniques to fix the error. Let’s take a look at the detailed solutions that you can follow to resolve the error:

Solution 1: Run the Clean Installation of QuickBooks Desktop

To fix QuickBooks Desktop error 15103, uninstall the program and reinstall it without any leftover difficulties from prior installations. Before reinstalling the latest version, a clean install removes all previous QuickBooks files to prevent corrupt files or registry issues from obstructing updates.

Start by removing the QuickBooks desktop from your computer.
Following that, download the QuickBooks Clean Install Tool on your computer.
You should rename the folder where you installed QuickBooks Desktop.
If the error is still there after renaming, try reinstalling the software.

Solution 2. Verify and Reset Internet Explorer Settings

During updates, QuickBooks depends on Internet Explorer to connect to the internet. This error might occur in QuickBooks if your Internet Explorer settings are incorrect. The problem might go away if you reset these settings.

After opening Internet Explorer, select the “Tools” menu and then “Internet Options.”.
Go to the Security menu, then choose Reset All Zones to Factory Settings.
Click Restore Advanced Settings after you’ve gone to the Advanced tab.
Under “Security,” scroll down until you see the option to enable SSL 2.0 and SSL 3.0.
Following that, click on Apply and then OK.
Try upgrading QuickBooks once more after restarting your computer.

Solution 3. Verify the Digital Signature Certificate of QuickBooks

Error 15103 might occur if QuickBooks is unable to complete updates due to an invalid or missing digital signature certificate. You can fix the problem by checking and upgrading this certificate.

Usually, you may find the QuickBooks executable file (QBW32.exe) under the C:\Program Files\Intuit\QuickBooks folder.
Access the properties of QBW32.exe by right-clicking the file.
To view details on Intuit, Inc., go to the Digital Signatures tab and choose the company.
After that, select Install Certificate from the View Certificate menu.
After you’ve followed the on-screen instructions to install the certificate, click Finish.

Solution 4. Run QuickBooks in Administrator Mode

If the software does not have the appropriate administrator permissions to finish updating QuickBooks, then you may see error 15103. Bypassing permission constraints that could hinder updates is possible when running QuickBooks in Administrator Mode, which provides it full access to system resources. By doing it this way, you can be certain that QuickBooks has permission to install itself without hiccups, replace files, and modify the registry.

Shut down QuickBooks if it’s running.
Locate QuickBooks on your computer’s desktop and right-click on it.
Following that, click on the “Run as Administrator” option.
To check if the problem still exists, try running the update again.

Solution 5. Configure Windows Firewall and Security Settings

If your security software, such as Windows Firewall, prevents QuickBooks from updating, you may encounter error 15103 in QB Desktop. Security settings may mistakenly flag update files or connections as threats, causing QuickBooks to become stuck during the update process. If you’re having trouble fixing this error, try adjusting your firewall and security settings so QuickBooks can connect. This will ensure that your firewall and security settings do not block updated files and internet connections.

To set up QuickBooks on your firewall, follow the steps outlined below:

Select Windows Firewall from the System and Security menu in your computer’s Control Panel.
To open Windows Firewall settings, go to the menu on the left and click Advanced Settings.
Pick New Rule from the context menu that appears when you right-click on Inbound Rules. A new dialog box will pop up where you may configure QuickBooks’ firewall rule.
Next, select Program as the rule type. Here you’ll have to navigate to the QuickBooks installation folder and pick the executable file, QBW32.exe.
To make sure QuickBooks can communicate with your network after you’ve chosen the program, click Allow the Connection.
Give the rule a memorable name, such as “QuickBooks Inbound Rule,” and follow the on-screen instructions to finish setting it up.
You need to do this again under Outbound Rules to make sure QuickBooks can receive and send outbound traffic.
To make sure the update finished successfully after firewall configuration, restart your computer and open QuickBooks again.

Using this technique, QuickBooks should have no trouble bypassing firewall limitations and accessing the internet for updates.

Solution 6: Manually Download and Install the Update Patch

When error 15103 appears during the standard update process, it may indicate that the update cannot proceed due to an issue with the software or internet connection. As a workaround, manually downloading and installing the update can bypass the problematic update process and resolve the error. By manually obtaining the update file, you’re directly installing the latest patch without relying on the software’s internal update function, which may be encountering errors.

Here’s how to manually download and install the latest update:

Open a web browser and go to the Downloads & Updates page on Intuit’s official website.
Choose your country from the drop-down menu to ensure you’re downloading the correct regional version. Then, select the specific product (e.g., QuickBooks Desktop Pro, Premier, or Enterprise) and the version (e.g., 2022, 2023) you’re using, so the site can provide the appropriate update.
After entering your details, click the Search button. This action will display the latest updates available for your selected QuickBooks version.
Find the most recent update or patch available for your QuickBooks product and version, and click Download. Save the update file to a location you’ll easily find, such as your desktop.
Once the download completes, double-click the downloaded file to start the installation process. Follow the on-screen prompts carefully to install the update, accepting all necessary terms and allowing the installer to overwrite outdated files.
After installation, reopen QuickBooks to confirm the software’s functionality and the resolution of the error.
