Software updates are essential, yet they can sometimes freeze or fail, often triggering QuickBooks error 15103. Although not limited to one issue, it falls under the broader 15XXX series, meaning the exact code may differ. You may also see a message stating:
“The update program cannot be opened.” or simply “Error 15103”
This problem typically stems from incorrect Internet or Windows Firewall configurations, an outdated QuickBooks version, and other factors explained below. Review this detailed guide to understand what may lead to QB error 15103 and the detailed troubleshooting steps.
When done, reopen QuickBooks, then your company file.
Go to Help > Update QuickBooks Desktop > Overview, then Update Now.
3. Map the Shared Download drive
You must map the Shared Download drive to access network files or folders when updating, so that the remote drive is treated as a local drive.
Press the Windows icon key.
In the Windows search field, type This PC and press Enter.
Select More (…) and click Map network drive.
Note: If you don’t see the Map network drive, right-click on This PCand click on Map network drive.
In Drive, choose a drive letter
You can either:
Enter the full path of the folder you wish to map or
Enter only the path to the computer where the file is hosted. Click Browse to find your folder.
Click on Reconnect at sign-in to keep the drive mapped every time you sign in to your computer.
Finally, select Finish.
4. Run the SFC scan
SFC scans for corrupted or missing system files and fixes them by replacing them with the correct versions from the local cache or installation media.
Press the Windows + X keys together on your keyboard.
Select Command Prompt (Admin) in the Quick Link menu.
NOTE: You can also run the System File Checker (SFC) from Windows PowerShell (Admin).
On the UAC prompt, click on Yes.
Now, type SFC /scannow in the command prompt and press Enter.
The System File Checker utility will automatically verify the integrity of Windows system files and also repair them if required.
When this is done, reboot your computer.
5. Enable the QuickBooks File Copy Service
The FCS is a background service that connects the files/programs with Intuit and enables the latest QuickBooks Desktop and payroll updates.
Press the Windows+R keys together on your keyboard.
In the Run prompt, type COMPMGMT.MSC and click OK.
The Computer Management window will open on your screen.
Click on Services and Applications.
Mark the checkbox for Services.
Scroll down the cursor until you find Intuit QuickBooks FCS and double-click on it.
Click on Startup type, then select Manual.
Select Apply and click OK.
When done, you will need to re-validate the payroll’s service keys. This will refresh your connection and ensure a seamless update.
Here’s how:
Navigate to Employees at the top.
Select My Payroll Service.
Click on Activate Service Key.
Now, highlight payroll in the Service Keys window, then click Edit.
Click Next until Finish displays on your screen.
6. Install a digital signature certificate
A digital signature certificate verifies the authenticity of the files you’re downloading electronically. Install the certificate for QuickBooks for easy updates:
Navigate to C:\Program Files\Intuit\QuickBooks.
Right-click on the QuickBooks program file, QBW32.exe.
Choose Properties.
Select Digital Signature and make sure Intuit is selected in the signature list.
Click on Details.
In the Digital Signature Details window, select View Certificate.
In the Certificate window, click Install Certificate.
Click Next once Finish is displayed.
Select Finish.
Restart your computer.
Open QuickBooks Desktop.
Now, try to download the updates again.
7. Configure Windows Firewall and security settings
Windows Firewall is an in-built security system that verifies the incoming and outgoing data via ports to protect your system. If the security applications detect something wrong, they will block those processes and the source, just as Windows Firewall might have blocked QuickBooks Desktop.
If something went wrong during the installation or Windows components are not interacting properly with the program, it could cause problems when you try to use it. To repair QuickBooks Desktop or fix the common installation issues, run the QuickBooks Install Diagnostic tool from the Tool Hub.
9. Re-install QuickBooks
Reinstalling QuickBooks Desktop removes the damaged program files or folders and replaces them with the new ones. This can resolve issues such as crashes, errors, and corruption without affecting your company’s data. It sets up a fresh installation, often by renaming the existing program folders to create new ones, ensuring the new version doesn’t conflict with the old one.
Conclusion
In conclusion, following the troubleshooting steps outlined above, you can identify the root cause of QuickBooks error 15103 and resolve it efficiently, ensuring your software remains up to date.
