  • Navigate to the “Company File Issue” section.
  • You can choose to “Run QuickBooks File Doctor” from that menu.

  • Run the file doctor program once it has been fully installed to identify the problem with the corporate file.

Solution 2: Give.ND and.TLG file New Names

The name of.TLG and.ND file extensions should be changed. The configuration files used by these extensions make it possible for QuickBooks Desktop to access company files on your network or in multi-user mode. For example, when opening QuickBooks Desktop, .ND or.TLG files may result in problems. Renaming these files does not result in data loss and can solve the error.

  • Go to your system and choose the company file folder. Intuition, QuickBooks, and Company Files are all located in the default location of C:\ Users\ Public\ Public Documents.
  • Find files with the name of your company file but with an extension.ND and.TLG, for instance: company_file.qbw.nd and company file.qbw.tlg
  • After that, select Rename by right-clicking on the. nd /.tlg file. 
  • Press the Enter key after adding the term “.old” to the end of the file extension. (Company file.qbw.nd.OLD, Company file.qbw.tlg.old)

Solution 3: Recover the Damaged Folder 

To recover a damaged folder, follow these steps to identify the problem. Recover the damaged folder by following the instructions-

  • Make a new folder initially on your C: disc.
  • Then access the folder containing the company’s files.
  • Discover the.qbw file. Now, right-click on the found file and choose the “Copy” option (for example, company file.qbw).
  • Paste the copied file into the newly created folder.
  • Windows access rights can be adjusted to allow sharing of the corporate files.
  • Open QuickBooks Desktop, and then open the file from the new location.

Solution 4: Configure Firewall Security

Your Firewall or Internet security program’s stringent settings may stop QuickBooks from contacting the server. Therefore, you must change your settings to prevent the Firewall from being restricted by QuickBooks. Carefully follow the directions provided below:

  • Configure your Firewall port settings first, as this is necessary for QuickBooks to communicate with the company file.
  • The next step is to set up exceptions for all of the Firewall’s ports.
  • Install an antivirus program or correctly set up one if you already have one.

Try the following troubleshooting method if the QuickBooks error code 6000 77 is still causing you problems.

  • Holding down the Ctrl key, select Run as administrator. Once you see the no company open window, let go of the Ctrl key.
  • Select “Open or restore company” from the menu.
  • Click the open button after choosing your company file from the list of options.

Solution 6: Take a Look at the Hosting Settings

If you use the business file with many users, check your hosting settings to ensure access is enabled.

Follow the instructions to revoke access if you are not utilizing the corporate file with numerous users.

  • Open QuickBooks and select the file.
  • It’s okay if the “Stop Multi-user Access” switch is switched on. And if it’s not then in that case, stop allowing access.
