  • Follow all the on-screen prompts to install and agree to the terms and conditions.
  • Once the installation finishes, click the QuickBooks Tool Hub icon twice to access the tool hub program.

Step 2: Run QuickBooks File Doctor Tool

  • At first, click on Company File Issues from the tool hub program.
  • Now, select Run QuickBooks File Doctor. It may take up to one minute for the file doctor to open. It is to be noted that if the QuickBooks File Doctor doesn’t open, look for QuickBooks Desktop File Doc and try accessing it manually.

  • After this, click Check your file (middle option only) and press Continue.

Windows Firewall settings, if not configured properly, can hamper every single operation on Windows. Below are the instructions to re-configure Windows Firewall settings so QuickBooks can run in multi-user mode.

System Firewall Settings

Step 1: Include Firewall Port Exception for QuickBooks

If you’re using multiple QuickBooks Desktop versions on the same computer, implement the following steps for each version.

  • Head to the Windows Start menu.
  • Enter “Windows Firewall” into the search box and open Windows Firewall Settings.
  • Select Firewall Advanced options from the left sidebar.
  • Under Advanced Settings, you get the inbound and outbound rules.
  • After this, hit right-click on Inbound Rules and then choose the New Rule option.

  • Hit right-click on Inbound Rules and then hit the New Rule tab.
  • Select Program and then press Next.
  • Afterward, choose This Program Path and then click Browse.
  • Locate and select any one executable file from the table listed below. Then click Next.
  • Moving ahead, choose Allow the Connection and then hit Next.
  • If prompted, you need to review that all profiles are marked. Later on, press the Next button.
  • Create a rule and name it “QBFirewallException(name.exe)“.
  • And lastly, repeat the same steps to create outbound rules.

Here’s a list of some executable files along with their locations:
