Why QuickBooks Keeps Crashing When Opening

Few things are more stressful than launching QuickBooks only to watch it freeze or crash instantly. This issue often stems from damaged program files, outdated Windows components, conflict with third-party apps, or corruption inside the company file.

What Causes QuickBooks to Crash?

  • Damaged QBWUSER.INI file

  • Corrupted QuickBooks installation

  • Outdated .NET Framework, MSXML, or Visual C++

  • Faulty or oversized company file

  • Incomplete Windows updates

  • Conflicting antivirus or firewall settings

How to Fix QuickBooks Crashing at Startup

  1. Rename the QBWUSER.INI file
    This forces QuickBooks to create a fresh configuration file.

    • Navigate to C:\Users\[YourUser]\AppData\Local\Intuit\QuickBooks

    • Rename QBWUSER.INI to QBWUSER.INI.old
      Try reopening QuickBooks.

  2. Use QuickBooks Tool Hub
    Download the latest version and run Quick Fix My Program.
    This is one of the fastest ways to resolve startup crashes.

  3. Repair QuickBooks Installation
    Go to Control Panel → Programs → Repair and choose QuickBooks.

  4. Disable aggressive antivirus temporarily
    Many security tools block QuickBooks files.
    Always re-enable protection after testing.

Understanding & Fixing QuickBooks Error 6190

Error 6190 typically appears when the company file and transaction log file (TLG file) don’t match. This mismatch happens frequently in multi-user mode.

Root Causes of Error 6190

  • Data mismatch between QBW and TLG

  • Company file opened in single-user mode on another workstation

  • Damaged transaction log

  • Network file hosting issues

How to Resolve Error 6190

1. Use QuickBooks File Doctor
This is the most effective method for resolving data mismatches.

2. Ensure Only One User Accesses the File
Close QuickBooks on all other systems and retry.

3. Rename the TLG File

  • Find your company file folder

  • Rename the .tlg file to .tlg.old
    This forces QuickBooks to recreate a fresh log file.

4. Verify Hosting Settings
Ensure only one server system has hosting enabled.

If the error persists, a professional file repair may be needed. Call +1-(855)-955-1942 for immediate assistance.

How to Change the Primary Admin in QuickBooks Online

Changing the primary admin is essential when ownership shifts or a team member leaves the company.

Steps to Change the Primary Admin

  1. Log into QuickBooks Online as the current Primary Admin

  2. Go to Settings (⚙️) → Manage Users

  3. Select Add User to invite the new admin if not already listed

  4. Once added, click the user → choose Make Primary Admin

  5. Confirm the transfer of rights through your email

If the primary admin is unavailable or no longer with the company, QuickBooks requires identity verification. This can be complex—support at +1-(855)-955-1942 can help you with admin transfer requests.

How to Delete a Customer in QuickBooks

Sometimes customers become inactive, duplicated, or unnecessary in your records, and you may want to delete or hide them.

Steps to Delete (Make Inactive) a Customer

  1. Go to Sales → Customers

  2. Select the customer you want to remove

  3. Choose Edit

  4. Click Make Inactive

  5. Confirm by clicking Yes

Important: QuickBooks does not allow full deletion if the customer has linked transactions. Instead, it marks them inactive.

If you need help cleaning up your customer list safely, the support team at +1-(855)-955-1942 can guide you through it.

Frequently Asked Questions

Q1. Why does QuickBooks crash repeatedly even after reinstalling?

Reinstallation doesn’t fix damaged Windows components or corrupted company files. Try renaming QBWUSER.INI or running QuickBooks Tool Hub.

Q2. Can Error 6190 damage my company file?

Not typically. It mainly prevents access but doesn't corrupt data unless ignored for too long.

Q3. How long does it take to transfer primary admin rights in QuickBooks Online?

Instant, if done manually. If done through Intuit verification, it may take 24–72 hours.

Q4. Can I permanently delete a customer from QuickBooks?

No, QuickBooks only allows you to make a customer inactive to preserve transaction history.
