What is QuickBooks Error 6190 816?

QuickBooks error code 6190 appears when a user tries to open the company file in single-user mode. If multiple users want to work on the file together, they must switch to multi-user mode. Further, the mismatch between the configuration file TLG) and the company file (QBW) can also lead to this error.

The various reasons why you get the message code “QuickBooks is unable to open this company file 6190” are as follows:

  3. Damaged ND and TLG files can also trigger the error 6190 in QB.
  4. An outdated QuickBooks Desktop becomes error-prone over time with minimal new features or security patches.
  5. A corrupt QuickBooks company file may fail to open, leading to the error 6190.
  6. A damaged, missing, or incomplete QuickBooks installation can cause this error.
  7. The folder where your company file is located is either damaged or exceeds the system path limitations.
  8. All the PCs might not be connected to the same company file because the file is in a different location.

  2. Verify the file location at the bottom of the company file list.

If different locations are detected on various computers, let’s establish a multiuser environment to ensure all users are connected to the same company file. Here’s the process:

  2. Set up folder permissions on your server computer, ensuring the folder with your company files has the necessary network permissions (Case 3 Measure 6)

Case 2: When You Access The File Locally

Local access to the company file means you are opening your company file on the same system where you have installed QuickBooks. If this is where you face the QuickBooks error 6190 816, we encourage you to take the following steps:

Measure 1: Change The Names of Your .ND And .TLG Files

Network Data (.ND) and Transaction Log (.TLG) are configuration files, which are a crucial part of QB files. They enable QuickBooks users to access company files in a multi-user or network environment. So, when these files get damaged, users fail to access them.

Renaming these files is one solution that helps recreate them when you scan with the Database Server Manager and open the company file. You don’t lose any of the QB data with this process.

Modify the Names of the .TLG & .ND Files

Modify the Names of the .TLG & .ND Files

  1. Access the folder holding the company files.
  2. Locate the files with .ND and .TLG extensions and the same name as your company file:
    1. ABCCompany.qbw.nd
    2. ABCCompany.qbw.tlg
  3. Right-click these files individually and tap the Rename option from the dropdown list. Now, add .OLD at the end, turning these files to:
    1. ABCCompany.qbw.nd.old
    2. ABCCompany.qbw.tlg.old
  4. Reopen QB and attempt to sign into your company file. Proceed to the next solution for QuickBooks error 6190 if this doesn’t work.

Measure 2: Access A Sample Company File

Addressing the error requires us to test whether the issue lies with QuickBooks or your company file. Therefore, following the steps to opening a sample company file is beneficial. If errors occur during the opening of the sample file, it indicates a potential problem with the QuickBooks installation. Follow the steps below:

  1. Click “Open a Sample File” in the No Company Open window and hit any sample file from the list.
  2. If the file opens successfully, proceed to the next solution for the error code 6190 in QuickBooks.

  2. It could be situated within too many folders, exceeding file path limitations.
