Step-by-Step Solutions to Fix Error 15223
Follow these in order to find the fix that works for your system.
Step 1: Configure Internet Explorer Settings
QuickBooks uses Internet Explorer's configuration to access the internet. If the settings are off, updates fail.
- Open Internet Explorer.
- Go to Tools > Internet Options.
- Under the Connections tab, click LAN Settings.
- Make sure Automatically detect settings is checked.
- Uncheck Use a proxy server (unless required).
- Click the Advanced tab.
- Scroll to the Security section.
- Make sure the following are checked:
- Use SSL 2.0
- Use SSL 3.0
- Use TLS 1.2
- Uncheck:
- Check for publisher’s certificate revocation
- Check for server certificate revocation
- Click Apply, then OK.
Restart QuickBooks and try the update again.
Step 2: Register DLL Files Manually
Corrupted or unregistered DLL files can cause this error. Re-registering them can resolve it.
- Close QuickBooks completely.
- Open the Run window (press Windows + R).
- Type the following and hit Enter:
- bash
- CopyEdit
- regsvr32 /s msxml3.dll
- Then type:
- bash
- CopyEdit
- regsvr32 /s wintrust.dll
- You won’t see confirmation, but it should complete silently.
Reopen QuickBooks and try updating again.
Step 3: Disable Antivirus and Firewall Temporarily
Security software can block the update process or QuickBooks’ internet access.
- Temporarily disable your antivirus.
- Disable the Windows Firewall:
- Go to Control Panel > System and Security > Windows Defender Firewall.
- Click Turn Windows Defender Firewall on or off.
- Select Turn off for both private and public networks.
- Try running the update again.
After testing, re-enable both antivirus and firewall.
Step 4: Run QuickBooks as Administrator
Running without admin rights can prevent certain update actions.
- Close QuickBooks.
- Right-click the QuickBooks icon.
- Choose Run as administrator.
- Try the update again.
Step 5: Clean Up Your System Files
Sometimes, damaged files interfere with QuickBooks updates.
- Type cmd in the Windows search bar.
- Right-click Command Prompt, choose Run as Administrator.
- In the command window, type:
- bash
- CopyEdit
- sfc /scannow
- Press Enter. This will scan and repair corrupted system files.
Once finished, restart your computer and try the payroll update again.
Step 6: Use QuickBooks Tool Hub
QuickBooks Tool Hub includes repair tools that can fix common errors.
- Download the latest QuickBooks Tool Hub from Intuit’s official site.
- Open it.
- Click Program Problems and run Quick Fix my Program.
- You can also use Network Issues and File Doctor to scan for broader problems.
Retry the update after using the tools.
Step 7: Reinstall QuickBooks Using Clean Install (If Needed)
If none of the above work, a clean install might be necessary.
- Uninstall QuickBooks via Control Panel.
- Download and use the Clean Install Tool from the Tool Hub.
- Reinstall QuickBooks Desktop using your license key and version.
Be sure to back up your company files first.
Q&A: QuickBooks Payroll Update Error 15223
Q: What exactly does Error 15223 mean in QuickBooks?
A: It means QuickBooks couldn’t complete a payroll or software update due to security or configuration issues—usually related to Windows, internet settings, or blocked connections.
Q: Can I still use QuickBooks if this error shows up?
A: Yes, but you won’t be able to get the latest payroll tax tables or software fixes until the update goes through.
Q: Do I have to use Internet Explorer? I don’t even open it.
A: Yes, QuickBooks uses Internet Explorer’s settings behind the scenes—even if you use Chrome or Edge. That’s why its configuration matters.
Q: Will disabling antivirus or firewall harm my system?
A: Temporarily disabling them for testing is safe if you’re not browsing the internet during that time. Just remember to turn them back on right after.
Q: What are DLL files and why do they matter?
A: DLLs (Dynamic Link Libraries) are system files used by programs to run specific functions. If they’re not registered correctly, QuickBooks can’t perform updates.
Q: What is TLS and why should I enable TLS 1.2?
A: TLS (Transport Layer Security) is a protocol that secures internet communication. TLS 1.2 is required by Intuit’s servers. If it’s disabled, QuickBooks can't connect properly.
Q: What’s the difference between Quick Fix my Program and File Doctor in the Tool Hub?
A: “Quick Fix my Program” resolves general app issues. “File Doctor” checks your company file and network for corruption or connection issues.
Q: Do I need to uninstall QuickBooks to fix this?
A: Usually not. Try the first six steps before considering a clean reinstall. Most issues are fixed without removing the software.
Q: How long does the SFC scan take?
A: The sfc /scannow command can take 10–20 minutes depending on your system. It scans for and repairs corrupted Windows files.
Q: Can I prevent this error in the future?
A: Yes. Keep QuickBooks updated, maintain clean system settings, don’t disable TLS 1.2, and ensure antivirus software is configured to allow QuickBooks through the firewall.
Final Thoughts
QuickBooks Payroll Update Error 15223 is usually tied to internet or security settings. It’s a frustrating but fixable problem, especially if you follow the steps above in order.
