QuickBooks users may experience a terrible and inconvenient notification, 'QuickBooks Has Stopped Working,' which halts the efficient financial and accounting processes. This error message implies that QuickBooks, a business accounting software, has frozen or stalled and is, therefore, useless. 
 
There are various explanations related to this error. However, they are mainly associated with the program environment. Common causes include problems with the Windows operating system, incompatibilities with third-party applications, corrupted company data, damaged software files, and insufficient system resources. Users can try a few different fixes to fix the QB not working issue.

Why is QuickBooks Not Functioning Properly?

The two major causes of QuickBooks not responding are listed in this section.

1. The error message may result from an incorrectly executed or insufficient installation of QuickBooks Desktop. The software’s operation may crash, eventually leading to issues while carrying out crucial bookkeeping and financial operations.
2. If the QBWUSER.ini file is damaged or missing, QuickBooks may stop functioning. Issues within the company file will prevent you from utilizing the QB data. Functionality can frequently be restored, and the QuickBooks running slow issue can be resolved by renaming the QBWUSER.ini file.

Try These Fixes for the QuickBooks Not Responding Issue

If your QuickBooks does not respond, you must carefully review these two methods to fix the issues.

Solution 1: Fix the Incorrect Installation of QB

You need to use the QuickBooks Install Diagnostic Tool carefully to fix the QB Desktop issues that are not working properly.

Step 1: Make Use of the Install Diagnostic Tool from Tool Hub

1. Launch the Tool Hub for QuickBooks. 
2. From the Tool Hub menu, choose 'Installation Issues.’
3. 'QuickBooks Install Diagnostic Tool' should launch after you click on it. 
4. Once done, you must start your PC again to save the latest changes.

Step 2: Fix QuickBooks Desktop 

1. Enter Windows as an admin.
2. Head to the Control Panel via the Windows Start menu.
3. Next, choose the Programs and Features option and click 'Uninstall a Program.' 
4. From the list, choose QuickBooks, and then click 'Repair.'

Solution 2: Rename the QBWUSER.ini File

If your QBWUSER.ini file is damaged or missing, renaming it might resolve the error. However, altering the QBWUSER.ini file will delete the list of previously opened company files, requiring you to reopen your business file again. If your file opens, the issue might be a damaged folder or folder permissions.

To rename the file:

1. Navigate to the QBWUSER.ini file's saved folder. You must enable hidden files and folders if the folder is not visible.
2. Now try changing the file name by choosing Rename.
3. Add ".old" to the end of the file name (for example, QBWUSER.ini.old). 
4. Rename the EntitlementDataStore.ecml file as well.
5. Reopen QuickBooks Desktop.
6. If QuickBooks opens after renaming either the QBWUSER.ini or EntitlementDataStore.ecml file, try opening a sample company file. 

After reading the complete guide, you will know how to fix the QuickBooks has stopped working problem. We recommend that you take a thorough look at all the steps. Backing up data and using QuickBooks Tool Hub can help resolve the issue quickly and efficiently.
