Error -6010, -100: Your QuickBooks installation may have been modified

While opening QuickBooks Desktop, the following error appears:

Why this is happening

This message can occur in a number of different situations:

  • The .ND (Network Device) file gets disassociated or disconnected from the .QBW and .TLG files.

  • You are running NOD32 Antivirus Software with Internet Monitor (IMON) enabled on the computer that contains the QuickBooks  Desktop data file.
    Any other antivirus with Internet monitoring could cause a similar error message in QuickBooks Desktop because it is acting as a firewall.

  • Some Registry cleaning programs, such as Fix It Utilities, can also cause this error.

  • You have a standalone PC installation of QuickBooks Desktop on a computer running Norton Protection Center.

How to fix it

Intuit recommends more than one solution for this problem. The first solution may solve your problem, or you may need to try all of them to resolve the issue. For best results, perform the solutions in the order shown.             

Solution 1:   For a standalone PC install of QuickBooks Desktop

  1. Choose File > Utilities > Stop Hosting Multi-User Access.
  2. Close and reopen QuickBooks Desktop. QuickBooks Desktop should now open without error.

Solution 2: Rename the .nd file associated with the company data file:

  1. Search the computer for files with extension .nd (Example: *.nd).
  2. Locate the .nd files with the name of the company having trouble opening.
  3. Right-click the .nd file, click rename and type old at the end ( for example, company.nd would become company .nd.old).
  4. Open QuickBooks Desktop. 

Solution 3: If you are running NOD32 Antivirus Software with Internet Monitor (IMON)

  1. On the computer where the QuickBooks Desktop data is stored, find the NOD32 program.
  2. Disable IMON functionality.
  3. Reboot the computer.

Solution 4: Run reboot.bat

If issue continues, or you do not have IMON software installed, run reboot.bat.

Solution 5: Perform a clean installation of QuickBooks Desktop
