How to Troubleshoot QuickBooks Error 15270 When Updating the Software? 

QuickBooks error 15270 often occurs when the update process is interrupted or when the system lacks proper access. To fix this issue, follow the troubleshooting steps below in order.

1. Download the updates as an administrator 

Without admin rights, QuickBooks cannot modify program files, apply patches, or access protected folders. Ensure to get the updates with the proper set of permissions: 

  • Close all the company files and QuickBooks Desktop. 
  • Right-click on your QuickBooks Desktop icon and choose Run as Administrator.
Run as Administrator
  • On the UAC prompt, “Do you want to allow this program to make changes to your computer?” click Yes.
  • Now, get the QuickBooks Desktop product updates. 
  • Try to get the payroll tax table updates again. 

2. Run Quick Fix my Program

The Quick Fix my Program shuts down all the lingering QuickBooks processes running in the background and then runs a quick repair to the program. 

  • Open the QuickBooks Tool Hub.
  • In the left pane, choose Program Problems.
  • Hit on Quick Fix my Program.
Quick Fix my Program
  • Let the utility run for some time, then try again to get the updates.

3. Map the Shared Download drive correctly 

If the shared download location is not mapped properly, QuickBooks may fail to locate the update files, triggering Error 15270. Ensure the path is correctly mapped before downloading updates.

The steps below apply to the Windows 11 OS:

  • Press the Windows logo on your keyboard. 
  • Type This PC in the search bar and choose This PC from the search results. 
  • Choose More (…), then click on Map network drive.

Note: If you don’t see the Map network drive option, right-click This PC and choose  Map network drive.

  • Choose any drive letter in the Drive.
  • You can either:
  • Type the full folder path you wish to map or  
  • Enter only the computer path where you host the file from, and choose Browse to find the folder
  • Hit on Reconnect at sign-in to make sure the drive is mapped each time you sign in to the computer. 
  • Finally, click Finish

4. Install a digital signature certificate 

QuickBooks requires a valid digital signature certificate to verify update files. Installing it can often resolve Error 15270: 

  • Navigate to C:\Program Files\Intuit\QuickBooks.
  • Right-click on the QBW32.exe file, then select Properties.
  • Select Digital Signature and ensure that Intuit is selected in the signature list.
  • Click on Details.
  • Select View Certificate in the Digital Signature Details window.
  • In the prompted Certificate window, select “Install Certificate.”
  • Hit Next until “Finish” is displayed, then click Finish.
  • Restart your computer.
  • Launch QuickBooks Desktop and try to download the QB update again. 

5. Configure the IE settings 

QuickBooks Desktop uses Internet Explorer settings to connect with Intuit servers. Incorrect settings may block updates, so configure them properly: 

Internet Explorer
  • Launch the Windows Start menu. 
  • Type Settings and press Enter
  • Navigate to Apps, then select Apps and Features.
  • Click on Manage Optional Features if you don’t see Internet Explorer as an option. 
  • Hit on Add A Feature.
  • Now, make sure Internet Explorer is in the list to add or enable. 
  • Finally, restart your computer to take the changes into effect. 

6. Configure the Windows Firewall settings 

To configure Windows Firewall for QuickBooks Desktop, open the Control Panel and go to Windows Defender Firewall. Select Advanced Settings and add Inbound and Outbound Rules for QuickBooks programs (e.g., QBW32.exe, QBDBMgrN.exe). Allow them through all ports. Save the changes and restart your system to ensure QuickBooks functions without firewall interruptions.

7. Enable the QuickBooks File Copy Service 

If the FCS service is disabled, outdated, or not running properly, it can block QuickBooks updates. Enable the service with the following steps: 

  • Press the Windows+R keys to open the Run prompt. 
  • In the prompted Run command, type COMPMGMT.MSC into and click OK.
  • Now, the Computer Management window will open on your screen, and select Services and Applications.
  • Mark the checkbox on Services
  • Scroll down the cursor until you see Intuit QuickBooks FSC as an option and double-click on the same.
