The error can be resolved using the techniques given below-

Solution 1- Use Windows selective startup (safe mode) to perform QB installation

QuickBooks installation might fail if the Windows firewall restricts the Windows installer from running. Other applications on your PC can also hinder the installation, which will cause this error code to flash on your screen. You can fix all these issues by running your system in a selective startup for installing QuickBooks. The safe mode only runs the apps and services essential for your PC, and the security software becomes ineffective. This reduces the chances of the Windows installer malfunctioning or getting blocked. Here are the steps to apply-

  1. Open the Run window using Windows + R keys.
  2. Type msconfig in the blank command field and press Enter.
  3. Navigate to the General tab of the system configuration window and click Selective Startup.
  4. Tap Load system services and go to the Services tab.
  5. Mark the checkbox beside Hide all Microsoft Services and click Disable All.
  6. Click on the Hide all Microsoft services checkbox again to unmark it.
