I'm here to help you fix Error 15103 in QuickBooks Desktop (QBDT), @smith2011.
This error code pops up when updating QBDT or downloading the latest tax table update. There are several reasons this can happen, including:
- The Shared Download drive wasn't mapped correctly
- A missing file or component for payroll updates
- Damaged windows files
- A firewall setting that can block payroll updates in QBDT
- QB File Copy Service (FCS) is disabled
- Unable to verify digital signatures
Before troubleshooting, you can check your firewall and internet security settings. Then, you can download the updates as an administrator by following these steps:
- Close your company files and QBDT.
- Right-click on the QBDT icon, then choose Run as Administrator.
- Click Yes on the message that asks, "Do you want to allow this program to make changes to your computer?"
- Download the newest QuickBooks Desktop product updates or the latest payroll tax table update again.
