3. Click End Task
4. Restart your system

Solution 2: Open QuickBooks Using the Desktop Shortcut Correctly

Launching QuickBooks improperly can trigger startup failure.

• Release Ctrl only when prompted to open or restore a company file

This prevents automatic loading of a corrupted company file.

Solution 3: Rename QBWUSER.ini File

3. Right-click and select Rename

QuickBooks recreates the file automatically.

Ensure the following:

Misconfigured Windows settings often prevent applications from launching.

If the new file opens successfully, repair the original company file using Verify and Rebuild Data Utility.
