What Is QuickBooks Error 1402?
QuickBooks Error 1402 is an installation-related error that appears when the installer is unable to read, open, or write to a specific registry key. The error message may display as:
- “Error 1402: Could not open key.”
- “Error 1402: Could not open key: UNKNOWN\Components…”
- “Error 1402: Could not open key: HKEY_LOCAL_MACHINE…”
What Causes QuickBooks Error 1402?
Although Error 1402 appears simple, it is usually triggered by deeper system-level problems. The most common causes include:
1. Registry Permission Issues
The QuickBooks installer must access certain registry keys during installation. If permissions are restricted—due to corrupted entries, a non-administrator account, or permission changes from other software—the installer cannot proceed.
2. Damaged or Incomplete Installation Files
If a prior QuickBooks installation failed, was interrupted, or left behind corrupted files, these leftovers can block a new installation.
3. Damaged Microsoft Components
QuickBooks depends on several Microsoft technologies:
- .NET Framework
- MSXML
- Microsoft Visual C++ Redistributables
If any of these components are broken or outdated, Error 1402 may occur.
4. Antivirus or Firewall Interference
Security programs sometimes mistake installation components for threats, especially when installers attempt to modify registry keys.
5. Corrupted Windows System Files
Windows system files may become damaged due to forced shutdowns, malware, disk errors, or incomplete updates.
6. Conflicts with Other Software
Other programs may lock registry keys or files that QuickBooks needs, leading to installation failures.
Recognizing Symptoms of Error 1402
Common signs you may experience include:
- The QuickBooks installation stops and displays “Error 1402.”
- QuickBooks cannot update or repair installation files.
- Registry-related warnings appear.
- System performance slows during installation.
- The message references Components or HKEY_LOCAL_MACHINE keys.
These symptoms often highlight registry permission issues or Windows component corruption.
How to Fix QuickBooks Error 1402: Step-by-Step
Before starting, follow these basic tips:
- Restart your system.
- Log in as an administrator.
- Temporarily disable antivirus software.
- Ensure you have a stable internet connection.
Method 1: Use QuickBooks Install Diagnostic Tool
This tool detects and repairs issues with Microsoft components such as .NET Framework, MSXML, and C++ Redistributables.
Steps:
- Download QuickBooks Tool Hub from Intuit’s official website.
- Open Tool Hub and choose Installation Issues.
- Run the QuickBooks Install Diagnostic Tool.
- Allow it to complete (10–30 minutes).
- Restart your computer and try the installation again.
This method resolves the error in most cases.
Method 2: Fix Windows Registry Permissions
If registry keys have incorrect permissions, the installer cannot access them.
Editing the registry can be risky. Always back up your registry before proceeding.
Steps:
- Press Windows + R, type regedit, and press Enter.
- Locate the key mentioned in the error message.
- Right-click the key → Permissions.
- Select Administrators, then allow Full Control.
- Choose Advanced → enable Replace all child object permissions.
- Apply changes and restart your computer.
Method 3: Reinstall Microsoft .NET Framework
Steps:
- Open Control Panel → Programs → Turn Windows features on or off.
- Uncheck all .NET Framework versions and restart.
- Reopen the same window and re-enable .NET Framework.
- Update Windows and try installing QuickBooks again.
Method 4: Install in Selective Startup Mode
Selective Startup reduces software interference.
Steps:
- Press Windows + R, type msconfig, and press Enter.
- Under General, choose Selective Startup and uncheck Load Startup Items.
- Go to Services, check Hide All Microsoft Services, then select Disable All.
- Restart your PC and run the QuickBooks installation.
After installation, revert your settings to Normal Startup.
Method 5: Repair Windows Components Manually
Repair MSXML:
Run these commands in an elevated Command Prompt:
- regsvr32 MSXML6.dll
- regsvr32 MSXML3.dll
Repair Visual C++ Redistributables:
- Open Control Panel → Programs and repair all Microsoft Visual C++ entries.
Method 6: Run System File Checker
In Command Prompt (Admin), run:
- sfc /scannow
- Restart and try installing QuickBooks again.
Method 7: Disable Antivirus/Firewall Temporarily
Some security tools block registry changes required by the installer.
Method 8: Perform a Clean Install
- Use QuickBooks Tool Hub → Clean Install Tool to remove corrupted files and reinstall QuickBooks.
Advanced Fixes
If the problem persists:
1. Reset System Permissions
Advanced users can use SubInACL or PowerShell to reset registry permissions.
2. Restore Windows System Image
Run these commands:
- DISM /Online /Cleanup-Image /RestoreHealth
- sfc /scannow
3. Create a New Windows Administrator Account
A corrupted user profile can block installation.
