- Add the word “OLD” at the end of each file name (e.g., “YourCompanyFileName.qbw.ND.OLD”).
- Open QuickBooks and try accessing your company file again.
4. Disable Antivirus or Security Software
Sometimes, antivirus or security software can interfere with QuickBooks and prevent it from connecting to the database. Temporarily disabling your antivirus or security software can help determine if it’s causing the problem.
- Open your antivirus or security software.
- Look for an option to temporarily disable it.
- Once disabled, try opening QuickBooks and accessing your company file.
- If the error is resolved, add QuickBooks as an exception in your antivirus or security software.
5. Run QuickBooks in Safe Mode
Running QuickBooks in Safe Mode can help you determine if another program is interfering with the software.
