About the error
This error code comes up on the screen in between the update or a few seconds after the update package is downloaded. This error indicates some incorrect system settings, which act as a barrier to the software update. QBDT won’t update until you take the necessary actions to counter the error and fix the issues that might trouble the software while downloading the new updates. Utilizing the software also becomes inconvenient as it’ll face compatibility issues due to its obsolete version and you’ll run into this error code whenever you try updating the software.
Primary Causes
This error code in the QBDT window indicates a threat to the software update and can also be generated when the connection to the internet breaks. The conditions on your PC which are liable to cause the occurrence of this QBDT update error are mentioned below-
- Windows Firewall restrictions can cause problems while connecting to the internet, accessing the update package, or when the software uses the system resources.
- Misconfigured User Account Control (UAC) settings can also stop the software update from installing on your PC.
- QBDT updates suffer directly when the internet connection lapses due to network connectivity issues.
- An outdated Windows version raises compatibility issues, which can hinder the software update.
- Incorrect timings on your system clock or insufficient privileges of your Windows account are also unfavorable for the software update.

Solutions
This error terminates the software update as soon as it develops and becomes repetitive if you try updating it continuously. You must apply the techniques listed below to fix the issues that can cause this error code to appear during the QBDT update-
Method 1- Adjust the Windows Firewall settings to prevent QuickBooks updates from getting blocked
Windows Firewall can hinder the QBDT functions, which generates numerous errors in the software. You must always check that your QuickBooks doesn’t get blocked by the Windows Firewall or any other security program active on your PC. If you have an antivirus on your PC, check its quarantine list to ensure none of the QB files or processes like QBUpdate.exe, QBW32.exe or QBDBMgrN.exe are isolated. A better option would be disabling your antivirus until the software updates are completely installed. You can let QBDT bypass the firewall settings by adding new ports for QuickBooks as shown in these steps-
- Search for Windows Firewall in the control panel and open its window from the search results.
- Click the Advanced Settings option and tap Inbound Rules.
- Hit the New Rule option in the next window and select Port.
- Tap Next and choose TCP from the TCP/UDP options on the screen.
- Navigate to the Specific Local Ports section and select the firewall ports according to your QB product version using this list-
- QuickBooks Desktop 2020 and later: 8019, XXXXX.
- QuickBooks Desktop 2019: 8019, XXXXX.
- QuickBooks Desktop 2018: 8019, 56728, 55378-55382.
- QuickBooks Desktop 2017: 8019, 56727, 55373-55377
- Click Next after you fill in the correct port number and select Allow the connection.
- Tap Next and mark all the user profiles if a dialogue box appears.
- Create and give the new rule any desired name and repeat all these steps again after selecting Outbound Rules instead of Inbound Rules.
- Try downloading the QBDT payroll updates again.
If you run into the error code again during the software update, check out the next solution.
Method 2- Set up the UAC settings correctly on your Windows
User Account Control or the UAC settings are employed by Windows to protect the system settings from getting changed by applications on your PC. Installation of every new update or application can interfere with the system settings and can arrange them according to their requirements. UAC settings prevent this from happening, which can sometimes cause problems while installing genuine updates and applications. QuickBooks develops this error when the update package cannot be extracted due to misconfigured UAC settings on your Windows. Use the following steps to configure the UAC settings on your PC-
- Use the Gear (settings) icon in the Windows Start menu to open the control panel.
- Select the Accounts option and go to the User Accounts menu.
- Tap Change User Account Control settings to reveal a slider used to control the settings.
- Click and drag the slider to Never Notify before the QBDT update to turn off the settings.
- After completing the QBDT update, you can turn the UAC settings on by moving the slider beside Always Notify.
If the software update fails even after fixing the UAC settings, move to the next solution.
Method 3- Change the DBSM account type to admin and install the latest updates of your Windows
QuickBooks updates can also fail due to a lack of admin rights of your Windows account, which creates problems while accessing the update package from the system drive or utilizing the system resources. Damaged Windows components (MSXML & .NET Framework) can also lead to failure while installing the payroll updates, but you are advised to get professional help to fix the components. You can provide admin rights to your Windows account and download the latest Windows updates to prevent issues as discussed in these steps-
- Go to the User accounts option from the control panel again and search for the QBDataServiceUserXX for the QB product version you use.
- Click the Account type option and select Administrator.
- Tap Change Account type and hit the Apply option to save the settings.
You must now proceed to update your Windows to its latest version to prevent compatibility issues with QBDT, which can interrupt the software updates. Use these steps-
- Navigate to the Update & Security option in the control panel menu and select Windows Update in the next window.
- Tap Check for updates and wait until the system finds the latest Windows version available for download.
- Hit Download and Install and let the Windows update complete.
- Open QuickBooks to download its updates when the system reopens after the Windows update.
If the software still displays the error code during the update process, move to the next solution.
Method 4- Arrange the TLS settings correctly and fix your system clock
QBDT updates can instantly fail if the internet connection lapses or the Intuit servers stop responding. This can happen due to incorrectly set TLS settings or your system settings. Transport Layer Security is usually for keeping your data safe when it is transferred over the internet, but can also block the internet access of Windows applications. You can ensure the QBDT doesn’t get blocked by the TLS by fixing the settings as shown in these steps-
- Open Run using the Windows + R keys and remove the auto-filled data in the command field.
- Type ‘inetcpl.cpl’ correctly and press Enter to open the Internet Options window.
- Go to the Advanced tab and move down the list to locate the TLS settings.
- Only mark the Use TLS 1.2 checkbox and make sure other TLS settings are unchecked.
- Hit Apply before closing the Internet Options window to save the settings.
After the TLS settings are fixed, you must now set up your system clock timings. Intuit servers always try to sync the update timings with the system clock, and the software can develop issues if the clock isn’t accurate. You can fix the timings using the steps given below-
- Right-click the clock you see on the taskbar and select Adjust date and time.
- You can select the Set time automatically option or adjust the timings manually.
- Save the settings after the time & date are set and try updating your QuickBooks Desktop.
If the error is still not gone and stops the payroll update, move to the next solution.
Method 5- Fix the technical glitches of your QBDT using the Quick Fix My Program tool
QuickBooks can randomly fall prey to internal issues that can stop it from executing its functions. Intuit has created a QB tool hub for users to diagnose and sort out minor issues automatically. You must also scan your QBDT to ensure the payroll updates aren’t failing due to internal issues-
- Open your device’s QuickBooks Tool hub window and click the Program Problems option at the top.
- Select Quick Fix My Program in the drop-down list and let the tool fix the minor issues in your QBDT.
