How to Fix QuickBooks Desktop Error 1402

Here are several effective methods you can use to fix the issue. Follow each step carefully for the best results.

Step 1: Use QuickBooks Install Diagnostic Tool

The QuickBooks Install Diagnostic Tool can automatically identify and fix many installation-related problems.

1. Close QuickBooks and all background applications.
2. Download and install the QuickBooks Tool Hub (if not already installed).
3. Open the Tool Hub and click on the Installation Issues tab.
4. Select QuickBooks Install Diagnostic Tool and let it run.
5. Once the process is done, restart your computer.

This tool repairs damaged Microsoft components required by QuickBooks, such as .NET Framework, MSXML, and C++.

Step 2: Update Windows

Installing the latest Windows updates ensures that your system has all the components needed for QuickBooks.

1. Press Windows + I to open Settings.
2. Go to Windows Update and click Check for updates.
3. Install all available updates and restart your system.

After updating Windows, try installing QuickBooks again.

Step 3: Repair Microsoft .NET Framework

QuickBooks relies heavily on Microsoft .NET Framework for smooth operation. If it’s damaged or incomplete, you’ll need to repair it.

1. Open the Control Panel.
2. Click Programs and Features.
3. Select Turn Windows features on or off.
4. Ensure that .NET Framework 3.5 and 4.8 are both checked.
5. If they are already checked, uncheck them, restart your system, then recheck them and restart again.

This process resets the .NET Framework and helps fix installation issues.

Step 4: Give Full Permissions to Registry Keys

When the installer can’t access certain registry keys, you may need to manually grant permission.

1. Press Windows + R, type regedit, and hit Enter.
2. Find the registry key mentioned in the error message.
3. Right-click it and choose Permissions.
4. Click Add, type your username, and select Full Control.
5. Click OK to save changes.

Be cautious while editing the registry. Making incorrect changes can affect your system. If you’re unsure, contact QuickBooks support at +1-833-654-8360 for professional help.

Step 5: Disable Antivirus and Firewall Temporarily

Your antivirus or firewall might block QuickBooks installation files.

1. Temporarily disable your antivirus protection.
2. Go to Control Panel > System and Security > Windows Defender Firewall.
3. Click Turn Windows Defender Firewall on or off.
4. Select Turn off Windows Defender Firewall for both private and public networks.
5. Try installing QuickBooks again.

After successful installation, re-enable your antivirus and firewall for security purposes.

Step 6: Use Selective Startup Mode

Running Windows in selective startup mode ensures that third-party programs don’t interfere with QuickBooks installation.

1. Press Windows + R, type msconfig, and press Enter.
2. Go to the General tab and choose Selective startup.
3. Uncheck Load startup items.
4. Go to the Services tab, check Hide all Microsoft services, then click Disable all.
5. Click OK and restart your computer.
6. Install QuickBooks again.

After installation, return to msconfig and select Normal startup.

Step 7: Reinstall QuickBooks Using Admin Rights

Installing QuickBooks with administrator privileges ensures that the installer can access all required files.

1. Right-click the QuickBooks setup file.
2. Choose Run as administrator.
3. Follow the installation instructions.
4. Restart your computer once the process finishes.

This helps bypass permission restrictions that cause Error 1402.

Step 8: Repair Damaged Windows Components

If Microsoft components like MSXML or C++ Redistributables are damaged, repair or reinstall them.

1. Go to Control Panel > Programs and Features.
2. Find Microsoft Visual C++ Redistributables and MSXML components.
3. Right-click each and choose Repair.
4. Restart your system after completing repairs.

Then try to reinstall QuickBooks Desktop.
