Error -6000, -77 – File Stored in Invalid Location

Likely Cause: The company file is stored in an external drive, restricted folder, or a path that QuickBooks cannot fully access.

Recommended Fix

    Avoid storing the file on external drives or network paths unless specifically configured.

  4. Ensure your QuickBooks version is up to date before attempting to reopen the file.

Error -6010, -100 – File Accessed Incorrectly

FAQs: Fixing QuickBooks Desktop Pro Errors

Why does QuickBooks Desktop Pro freeze or lag on my new Windows 11 PC?

Freezing or lagging often occurs when your system lacks sufficient RAM (minimum 8 GB, ideally 16 GB), or you’re running an older version of QuickBooks not optimized for Windows 11. Ensure you're using a 64-bit OS and a compatible version like QuickBooks 2021–2024.

What should I do if I get “Error 3371, Status Code -11118” when opening QuickBooks?

This error means your license file is damaged or missing. Use the QuickBooks Tool Hub > Installation Issues > Fix Error 3371. If that doesn’t work, manually delete the EntitlementDataStore.ecml file and re-register MSXML.

Can I fix installation errors like Error 1904 or 1603 without reinstalling QuickBooks?

Yes. Run the Install Diagnostic Tool from the QuickBooks Tool Hub, ensure you're installing as an Administrator, and temporarily disable any antivirus/firewall. Also, run Windows Updates to repair supporting Microsoft components like .NET Framework and MSXML.

I’m getting Error 1402 during installation. What does it mean and how do I fix it?

Error 1402 means QuickBooks couldn't access a registry key due to permission issues. Run the installer as Administrator, or manually adjust registry permissions in regedit (advanced users only). Use the Tool Hub as a safer first step.

Why does multi-user mode fail for my small business even after setup?

Multi-user mode errors usually stem from improper network setup or insufficient server RAM (need at least 8 GB for 1–5 users). Make sure hosting is enabled only on the server and that all users are on the same QuickBooks version and Windows network.

What’s the fastest way to reach QuickBooks support when I hit an error like H202 or install failure?

For urgent issues like error codes or failed installs, call 1-800-446-8848 (24/7 support). For less urgent help, use in-product support via Help > Contact Us or the QuickBooks Tool Hub. Pro Plus users get priority, including remote expert access.
