Let’s walk you through this detailed guide to learn why you cannot download the payroll or QuickBooks desktop update and the suitable troubleshooting methods. 

What Causes QuickBooks Update Error 12045? 

QuickBooks update error 12045 usually occurs when QuickBooks Desktop is unable to connect to the internet to download updates. This error is typically related to network connectivity or to security settings that block QuickBooks from accessing update servers.

Here are the most common causes:

• Incorrect date and time on your system
• Incorrectly configured internet connection settings
• Windows Firewall, antivirus, or other security applications might be blocking the updates
• Automatic update might not be working 
• Third-party applications or processes may hamper the software updates

Methods to Troubleshoot QuickBooks Error 12045 When Updating QB or Payroll 

Here are proven and effective troubleshooting steps to help you quickly resolve QuickBooks error 12045 and restore your update functionality.

1. Check the system date and time on the computer

If your computer’s date or time is wrong, it can disrupt the update process.

To verify and correct your system date and time:

• Right-click the clock on your desktop, then choose Adjust Date/Time.
• Click Change date and time, then enter the correct current date and time.

• Click OK, then click OK again to confirm.
• Close QuickBooks Desktop and open it again.
• Attempt to update QuickBooks Desktop once more.

2. Check your Internet Connection Settings

Problems with your internet connection may be preventing the update from completing.

To check whether your connection is secure, open a web browser and go to the Chase banking website. If the page doesn’t load, QuickBooks won’t be able to download updates. Reach out to your internet service provider (ISP) for assistance.

If the website opens without issue, launch QuickBooks Desktop and follow these steps:

• Go to the Help menu and choose Internet Connection Setup.

• Select Use my computer’s Internet connection settings to establish a connection when this application accesses the Internet.
• Click Next.
• Choose Advanced Connection Settings.
• Open the Advanced tab and click Restore Advanced Settings.
• Click OK.
• Select Done.
• Try updating QuickBooks Desktop again.

Keep the following in mind:
Download managers or accelerators may disrupt the update process. Turn them off before attempting to download any updates. If you need assistance, reach out to your Internet Service Provider (ISP). If you’re connecting through dial-up, make sure your connection speed is at least 28.8 Kb/s.If you’re using America Online (AOL), try signing in with the main account username and confirm that Parental Controls are turned off. Visit AOL’s support resources for additional guidance.

3. Internet security or personal firewall application settings

Internet security programs and personal firewall settings can sometimes block or disrupt updates.

Check your antivirus and firewall configurations to ensure they allow proper access. Make sure that ports 80 and 443 are open, and that the following QuickBooks-related files are permitted through the firewall:

• AutoBackupExe.exe
• Dbmlsync.exe
• DBManagerExe.exe
• FileManagement.exe
• FileMovementExe.exe
• IntuitSyncManager.exe
• QBCFMonitorService.exe
• QBDBMgr.exe
• QBDBMgrN.exe
• QBGDSPlugin.exe
• QBLaunch.exe
• QBServerUtilityMgr.exe
• QBW32.exe
• QuickBooksMessaging.exe

In the rare case that ports 80 and 443 are already in use by other applications, the QuickBooks Database Server will automatically switch to an alternate port, 56719.

For detailed steps on setting up firewall exceptions for your specific version of QuickBooks Desktop, configure Firewall Security Settings for QuickBooks Desktop.

Warning: Due to the wide variety and complexity of firewall software, Intuit does not offer direct assistance for individual firewall configuration issues. If you need help, contact your network or system administrator, your firewall software provider, the manufacturer’s support resources, or a qualified IT professional.
