Microsoft Setup Bootstrapper stopped working while installing Office

Microsoft tried to speed up the installation of its products by implementing the latest technology. Before, we used executable files which were quite effective in installing the product with one click. Nevertheless, Microsoft uses Bootsrapper technology in Office 2019/2013/2016. Bootstrapper is responsible for initializing the program created with the library of compound programs.

Recently, when installing Microsoft Office, we faced the installation failure dilemma due to Bootsrapper technology. We got the following error:

3. At this point in the registry, as shown in the image above, right-click the AppCompatFlags key and select Export. Save the key as a registration document in a convenient place on your own system for backup. Click on the exact identical key, i.e. AppCompatFlags, and select Delete.

Now you can close Registry Editor and then restart your device.

After restarting your computer, you need to install Microsoft Office in a clean boot state.
