QuickBooks Error 6123, often displayed as Error -6123, 0, can prevent you from opening, restoring, or upgrading a company file. You may see a message saying that QuickBooks cannot open the company file. The problem can occur because of network issues, damaged company files, problems with QuickBooks processes, or an unsupported computer setup.
Fortunately, several simple solutions can help you troubleshoot the error and regain access to your company file.
What Causes QuickBooks Error 6123?
QuickBooks Error 6123 can have different causes depending on what you were doing when the error appeared.
Common causes include:
Damaged or corrupted company files.
Problems with network connections.
QuickBooks background processes not responding.
Issues with the QuickBooks installation.
Problems while restoring a company file.
Opening the company file incorrectly.
Firewall or security software interference.
Compatibility problems with the computer’s processor.
The error can occur when opening, upgrading, or restoring a company file.
Restart Your Computer
Start with a simple restart.
Close QuickBooks and other running applications. Restart your computer and wait for Windows to load completely.
Then open QuickBooks and try accessing your company file again.
A restart can clear temporary processes that may be preventing QuickBooks from opening the file correctly.
Open the Company File From QuickBooks
If you normally double-click the company file from Windows File Explorer, try opening it directly from QuickBooks instead.
Open QuickBooks Desktop first and select the option to open an existing company file.
Browse to the location of your .QBW file and select it.
Intuit specifically recommends opening the company file from within QuickBooks rather than Windows Explorer when troubleshooting Error 6123.
Run Quick Fix My Program
QuickBooks Tool Hub includes Quick Fix my Program, which can close background QuickBooks processes and perform a quick repair.
To use it:
Close QuickBooks.
Open QuickBooks Tool Hub.
Select Program Problems.
Choose Quick Fix my Program.
Wait for the process to finish.
Open QuickBooks again.
Intuit currently lists Error 6123 among the problems that QuickBooks Tool Hub can help troubleshoot.
Run QuickBooks File Doctor
If Quick Fix my Program does not resolve the problem, try QuickBooks File Doctor.
Open QuickBooks Tool Hub and select Company File Issues.
Choose Run QuickBooks File Doctor and select the affected company file. Allow the tool to check the file and repair common problems.
After the process finishes, reopen QuickBooks and try the company file again. Intuit recommends File Doctor as the next step when Quick Fix my Program does not resolve Error 6123.
Check Your Network Connection
If the company file is stored on another computer or server, check your network connection.
Make sure the host computer is turned on and the shared folder is accessible.
Try opening the company file location through Windows File Explorer. If you cannot access the folder, there may be a network or sharing problem.
You should also make sure that the computers are connected to the correct network.
Check Your Computer’s Processor
A less common but important cause of Error 6123 is an unsupported processor.
According to Intuit, QuickBooks Desktop is designed for computers using Intel or AMD processors. ARM-based computers using Snapdragon or Qualcomm processors may not be compatible with QuickBooks Desktop.
To check your processor, open Windows settings and look under Device specifications.
If your computer uses an ARM-based processor, consider using QuickBooks Desktop on a supported Intel or AMD computer, an authorized cloud-hosting environment, or QuickBooks Online.
Restore the Backup From a Local Drive
If Error 6123 appears while restoring a QuickBooks backup, check where the backup file is stored.
If the .QBB backup is on a network, external storage device, or online storage folder, move a copy to your local hard drive first.
Then try restoring the backup from the local location. Intuit recommends restoring the backup from the computer’s local hard drive when this error occurs during restoration.
Use a Portable Company File
If you are restoring a backup on a new computer and Error 6123 appears, creating a portable company file may help.
Open the original company file on the computer where it works.
Create a portable company file with the .QBM extension.
Move the portable file to the new computer and use QuickBooks to restore it.
Intuit recommends this approach for certain situations involving Error 6123 when moving company data to a new computer.
Check Your Firewall and Security Software
Firewall or security software can sometimes interfere with QuickBooks communication.
Check your firewall settings and make sure QuickBooks is allowed to communicate through the network.
Do not permanently disable your firewall just to fix the error. Instead, configure the appropriate permissions for QuickBooks and its required components.
Update QuickBooks
An outdated QuickBooks installation can cause compatibility and program problems.
Check for available QuickBooks updates and install the appropriate update for your version.
After updating, restart the computer and try opening the company file again.
Keeping QuickBooks updated can also help prevent other company file and program errors.
Make a Backup After Fixing the Error
Once you successfully open your company file, create a new backup.
This is particularly important if you used a repair tool or restored the file.
Keeping recent backups gives you a safer recovery option if the company file develops problems in the future.
