How to Repair Microsoft Setup Bootstrapper Has Stopped Working Error

admin / October 23, 2020

The Microsoft installer is no longer running. This is an error message that appears when you install MS Office 2007, 2010, 2013, 2016 or upgrade your Office to a newer version.

Microsoft has tried to improve the installation system by using an updated technology. Before seeing it, it was enough to install the executable file and one click was enough to install the product. Today Microsoft used a modern technology called “Bootstrapper” to install Microsoft Office 2013/2016.

Depending on the functionality, “Bootstrapper” initializes the application created with the “Composite Application Library”.

Before you begin to fix this problem, you need to create a recovery point to restore your system.

What is Microsoft Setup Bootstrapper?

What is the Microsoft installation bootloader? In Microsoft Office 2013, 216 and 2019 the loader is used to initialize an application created with the Composite Application Library, which simplifies the dependencies needed during the installation.

Reasons for stopping the Microsoft Bootstrapper installer

You can see that the Microsoft installation loader stopped working when trying to run programs in Microsoft Office package, and the Microsoft installation loader stopped working for various reasons. I now list some of them below:

  • Communication between the installer and MS servers is blocked by third-party anti-virus software.
  • Registry keys or installation files are damaged.
  • Conflict with IObit software.
  • The task scheduler is disabled in the registry editor.
  • The update process is interrupted by AppComparFlags.
  • Office installation is incompatible with Windows version.

Uninstall third-party antivirus software

Some users reported that in their case the problem was solved after removing their third-party antivirus package http://windowsbulletin.com/fix-microsoft-setup-bootstrapper-has-stopped-working/. It turns out that there are several overprotective antivirus programs (McAfee, Avast, possibly others) that block the functionality of Microsoft Office package update and cause an error in Microsoft Setup Boot Trapper that stopped working. .

If this scenario is applicable to your situation, simply disabling real-time protection in your security package may solve the problem. The steps to do this of course depend on the audiovisual package you are using.

Note, however, that some users have reported that the problem has not been solved until they have completely removed a third-party antivirus from their system. When you are ready to go that far, follow this article (here) to remove the security programs and make sure that all the remaining files are also removed.

If after working with a third-party security package you still receive the error message “The installer stopped working when you started the Microsoft installation” or if this method was not applicable, proceed to the following method.

Using the Troubleshooting utility

Step 1. Click the link below to go to the Microsoft support page and download the program installer and troubleshooter:

Depending on your system type (32-bit or 64-bit) click “Download” to download the fix.
For example, my system is 64-bit, so I chose to boot X64. If you are using a 32-bit system, you should choose to boot X86.

Step 2: Now click to start the fix, and check the “Apply the fix automatically” box.

Click Next to continue.

Step 3: Now wait for the Troubleshooter to detect all problems.

Step 4: Select the problem you have encountered. For example, here we have an installation problem. Click on Install.

Step 5: Wait until all installation problems are detected. When you are done, you will see a list of programs that have problems with the installation. Choose if it is on the list and click Next.

Step 6: If the program is not in the list, select “Not in the list” and click “Next”.

Step 7: You will then be asked if you want to remove the program or try other fixes. Choose as you wish.
