  1. Open QuickBooks Desktop.
  2. If another company file opens automatically, select File and then Close Company.
  3. Choose the option to open or restore an existing company file.
  4. Browse to the location of your company file, which typically has a .qbw extension.
  5. Select the file and try opening it.

If the error persists, proceed to the next solution.

 4. Restore the Backup From Your Local Drive 

If QuickBooks Error 6123 0 appears while restoring a backup, the file's storage location may be contributing to the problem.

If your backup is stored on a network drive, external drive, or online storage folder, copy it to a local folder on your computer first. Then, open QuickBooks and restore the backup from that location.

If you are restoring a backup on a new computer, Intuit also recommends creating a portable company file (.qbm) on the original computer and using it to restore your data on the new computer.

 5. Check Your Computer's Processor 

QuickBooks Desktop may not work properly on ARM-based computers, including systems using Snapdragon or Qualcomm processors.

To check your processor:

  1. Open the Windows Start menu.
  2. Search for About your PC.
  3. Open the system settings.
  4. Find the processor information under Device specifications.

If your computer uses an ARM-based processor, consider using a compatible Intel- or AMD-based computer, an authorized cloud-hosting environment, or QuickBooks Online.

 6. Check Network and Company File Access 

If the error occurs when accessing a company file over a network, verify that the computer hosting the file is available and that the required permissions are configured correctly.

Avoid moving or modifying the original company file without creating a backup. If the error persists after using the recommended tools, contact Intuit support for further assistance.

 Conclusion 

QuickBooks Error 6123 0 can interrupt accounting work when opening, restoring, or upgrading a company file. Opening the file through QuickBooks, running QuickFix My Program, using File Doctor, and restoring backups from a local drive are useful troubleshooting steps.
