What Causes Company File Error C 184 in QuickBooks? 

Before troubleshooting, it’s important to determine why you’re getting QuickBooks company file error C 184: 

  • Reports you are opening might be mismatched 
  • .ND and .TLG files might be damaged or corrupted 
  • The location where the company file is saved might not be the default
  • Possible damages, corruption, or common network connectivity issues 

5 Easy Solutions to Troubleshoot QuickBooks Error C 184 Instantly 

Let’s explore five easy and effective solutions that can help you troubleshoot and resolve QuickBooks error C 184 without hassle:  

1. Manual changes to mismatched reports

QuickBooks error C 184 typically occurs during leap years when February has 29 days. In such cases, the report date may fall outside the date range selected by the user. To fix this issue, you need to manually update or adjust the report’s date range.

2. Rename the .ND and .TLG files

The .ND and .TLG files are the configuration files that allow QuickBooks Desktop to access your company file in the multi-user environment. Any damage or corruption to these files can cause errors when opening QuickBooks Desktop or performing related operations.

To resolve this, rename these files so QuickBooks can create new files and replace them when you open the company file, or scan the company files using QuickBooks Database Server Manager.

  • Open the folder where you saved the company file. 

Default Location: C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files

  • Look for the files with the same name as your company file, but with the .ND and .TLG extensions. 

Example: company_file.qbw.nd, company_file.qbw.tlg

  • Right-click on the .ND and .TLG file and choose Rename.
  • Now, add the .OLD extension at the end of these files and press Enter

Example: company_file.qbw.nd.OLD, company_file.qbw.tlg.OLD

3. Move the damaged company file

If the error message continues to appear, try changing the location of your company file and follow the steps below:

  • Copy the company file and paste it into a different location on your computer.
  • After moving the file, update its path in QuickBooks.
  • Open the company file from the new location and check whether the problem has been resolved.
  • If the error still occurs, navigate to the QuickBooks installation folder and locate the company file with the .qbw extension.
  • Rename the file and add .OLD to the end of the file name.
  • You can also move the company file to another folder if the current one is damaged. Create a new folder, move the company file into it, and then update the folder path in QuickBooks Desktop.

4. Verify and Rebuild the company file data 

The Verify tool verifies company file data for potential damage and, if any is found, rebuilds the damaged data using the Rebuild Data utility:

a. Verify your company data 

Scan your company for possible errors or data damage using the Verify Data tool: 

  • Navigate to Window and select Close All
  • Go to the File menu. 
  • Choose Utilities.
  • Finally, click on Verify Data.

The Rebuild Data utility lets you repair the company file by rebuilding the damaged data. A backup is necessary before rebuilding.

Note: If you are an Assisted Payroll user, contact us before rebuilding the data. 

  • In the left menu bar, select File
  • Choose Rebuild Data.

  • Enter a new name in the File name and click Save
  • When you see the “Rebuild has completed” message, click OK

5. Run QuickBooks File Doctor 

The QuickBooks File Doctor utility verifies the company file for possible data damage and network connectivity issues. If anything is detected, it runs a quick repair on your company file.

Important Note: You must download and install QuickBooks Tool Hub (1.6.0.8) in the most recent version available. 

  • Launch the QuickBooks Tool Hub. 
  • Go to Company File Issues in the left menu bar.
  • Click on Run QuickBooks File Doctor. The tool can take up to a minute or more to open the file doctor. 
Run QuickBooks File Doctor

Note: If the QuickBooks File Doctor doesn’t open, search for QuickBooks Desktop File Doc and open the tool manually. 

  • In QuickBooks File Doctor, choose your company file from the dropdown menu. If you don’t see the company file, click Browse and search to locate it.
  • Select Check your file and then click Continue.
  • Enter the QuickBooks admin password, then click Next

The scan time usually depends on your company file size and may take 10-15 minutes. It may even say the scan is unsuccessful even after fixing the issue. When the scan finishes, open QuickBooks Desktop and your company file.
