How To Easily Fix Bootstrapper Has Stopped Working Error In Windows?
Run Program Install And Uninstall Troubleshooter
According to several users, the Microsoft Program Install and Uninstall troubleshooter has assisted them in fixing the Microsoft Office Bootstrapper error.

You can download and run the Program Install and Uninstall troubleshooter in the following steps, even if it is not included with Windows.
1 – Go to the download page for the Program Install and Uninstall Troubleshooter.

Disable Or Uninstall Third-Party Antivirus Software
Several users have reported that this issue is caused by overprotective third-party antivirus tools that prevent Microsoft Office’s installation. As a result, we recommend that you disable any third-party antivirus software installed on your computer. To do so, right-click the antivirus utility’s system tray icon and select an option for disabling the shield.
Deleting antivirus software will likely ensure it does not conflict with Office’s installation procedure. If disabling security software doesn’t work, try uninstalling your third-party antivirus utility.
Run Program Compatibility Troubleshooter For Installation File

Re-enable Task Scheduler By Editing The Registry
The Re-enabling Task Scheduler by editing the Registry can fix this Bootstrapper error, according to users’ forum posts. So, this issue might be caused by a disabled Task Scheduler that Office services cannot access. Using the Registry Editor, you may do this to re-enable that utility.
1 – Select the Run Power User menu shortcut by clicking the Start taskbar button with your mouse’s right button.
2 – Next, in the Run dialogue, type regedit and click OK to launch.
3 – Open this registry key.

5 – Double-click the Start DWORD.
6 – Enter 2 in the Value data field for the Start DWORD.
7 – Choose OK to exit that DWORD window.
8 – Close Registry Editor and choose to restart your desktop/laptop.
Delete AppCompactFlag Registry Key
Here is another registry change fix that has worked for some users. It entails uninstalling any current Office installation on your computer and erasing an AppCompatFlags key in the Registry. The following steps will allow you to apply that probable Bootstrapper error resolution.
1 – Use Programs, Features, or the Microsoft Uninstall Tool to uninstall any Office software on your System. This Microsoft page contains a download option for that uninstaller utility and advice on uninstalling Microsoft Office in either case.
2 – Next, consider Registry Editor as recommended in the first resolution steps.
3 – Delete the current path in the Registry Editor’s address bar.
4 – Type this AppCompatFlags location into the URL box and hit Return.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags
5 – To back up the AppCompatFlags key, right-click it and select Export. Click Save after selecting a folder from which to export the key.
6 – Right-click AppCompatFlags and select the Delete option.
7 – Click the Yes confirmation button to erase that key and its subkeys.
8 – Restart Windows after closing the Registry Editor window.
Apply Clean Boot
Performing a clean boot will remove third-party startup items and services that automatically run in the background. It’s similar to booting Windows into safe mode, except it does not affect drivers. The “Bootstrapper has stopped working” error might be caused by background software conflicts, which this troubleshooting procedure will likely resolve. To apply a clean boot, use MicrosoftConfig and Task Manager to disable all third-party starting items and services. When you’ve configured the clean boot, all you have to do is restart Windows. Next, after clean-booting Windows, see if the Bootstrapper error occurs.
Several software products have been verified to conflict with Microsoft Office, resulting in the Bootstrapper error. Three software programs that potentially conflict with Office include IOBit Uninstaller, Advanced System Care, and Citrix Virtual Desktops (previously XenDesktop). Try uninstalling any software bundles to ensure they don’t cause any issues.
