What Causes the QuickBooks Unable to Complete this Operation Error?

QuickBooks is a popular accounting software that helps small and medium-sized businesses manage their finances, invoices, payroll, and taxes. However, sometimes QuickBooks users may encounter an error message that says “QuickBooks is unable to complete this operation and needs to restart”.

This error can occur due to various reasons, such as:

  • Corrupted or outdated QuickBooks software
  • Invalid or duplicate names of items, accounts, or customers in the QuickBooks company file
  • Damage or corruption in the QBWUSER.ini file or the QuickBooks company file
  • Network issues or firewall settings that block QuickBooks from accessing the company file
  • Other software or hardware issues that interfere with QuickBooks performance

This error can be frustrating and cause data loss or corruption if not resolved quickly. Therefore, it is important to troubleshoot the error and fix it as soon as possible.

How to Troubleshoot “QuickBooks is Unable to Complete this Operation” Error?

Method 1: Download QuickBooks Updates

Download and install the latest updates for your QuickBooks software. The updates may contain bug fixes and improvements that can resolve the error and enhance your QuickBooks performance. To download and install QuickBooks updates, follow these steps:

  1. Open QuickBooks and go to the Help menu

  7. Restart your computer and check if the error is resolved

Method 2: Check Name of Items in the Account

Another possible cause of the QuickBooks error is having invalid or duplicate names of items, accounts, or customers in your QuickBooks company file. This can confuse QuickBooks and prevent it from completing the operation. To check and fix the names of items in your account, follow these steps:

  1. Open QuickBooks and go to the Lists menu
  2. Select the list that you want to check, such as Chart of Accounts, Item List, or Customer Center

  3. Add .old at the end of the file name, for example, QBWUSER.ini.old
  4. Also, rename the EntitlementDataStore.ecml file in the same folder by adding .old at the end of the file name
  5. Close the File Explorer and open QuickBooks
  6. Open your company file and check if the error is resolved
