  • The installation files or registry keys in the device are damaged or corrupted.
  • Third-party antivirus software in the device blocks the syncing between MS servers and the installer.
  • Certain software conflicts.
  • AppComparFlags file blocking the updating process.
  • Office suite does not suit the currently running Windows version.
  • The Task Scheduler within Registry Editor is deactivated.

Step 6: Hit the OK button.

Step 7: Restart the PC after closing the Registry Editor.

Fix 5: Remove Third-party antivirus or conflicting programs

In some cases, the leading cause of the Microsoft Setup Bootstrapper has stopped working issue is due to conflict with specific programs. For example, some freeware cleanup software types or third-party antivirus software can block the regular functions that work in the system background for them to function as needed.

In these situations, removing these software types or disabling them momentarily is better. Then, you can run the Bootstrapper program without issues.

How to proceed?

Step 1: Tap on the Win + R keys on the keyboard.

Step 2: After the Run dialog box comes up, add the following command and press OK:

appwiz.cpl

Step 3: Find the third-party antivirus software or conflicting freeware under the Programs and Features page.
