  • Launch QuickBooks on one of your workstations.
  • Do not open your company file.
  • Instead, go to the File menu and hover over Utilities.

Host-Multi-User-Access

  • Right-click on the file and choose Copy.
  • Navigate to the Desktop, right-click anywhere on the desktop, and select Paste.
  • Hold down the Control key and then open the file.

Solution 8: Use a UNC Path Instead of a Mapped Drive

  • Right-click on the QuickBooks icon on the desktop and hold down the Ctrl key on the keyboard.
  • Choose Run as Administrator.
Run-QuickBooks-as-an-Administrator
  • Keep the Ctrl key pressed until the No Company Open window appears.
