Some Windows users have recently encountered the error code 9C59 when trying to install a certain update or when trying to update Internet Explorer.

If you are a Windows user, you already know very well how important Windows updates are. They fix system errors, fix bugs, speed up many system processes, and are generally a great way to optimize your PC. In most cases, Windows updates install automatically without any errors.

If you too have encountered this error code lately, you’ve come to the right place. In today’s article, you will learn how to fix Internet Explorer update error 9c59.

What is the cause of Windows Update error 9C59?

After thoroughly investigating this problem, it was found out that several different reasons can cause this error code. Here is a list of possible culprits that may be responsible for causing this error code:

TCP or IP blocks: another possible scenario, exclusively for Windows 10, is when corrupt temporary data interferes with an update of existing Microsoft-signed software. In this case, the old version of IE (usually Internet Explorer 9) must be uninstalled before creating a .bat file that can delete residual files from the previous installation.

Update restriction: Many Windows 7 users could not install Internet Explorer 11 because of an obvious limitation that seems to be indirectly caused by Windows Update. In this case, you can solve the problem by using a standalone installer to install the problematic browser on Windows 7.

Damaged system file: In some cases, this error may be a direct result of a corrupt basic system file, which affects the operating system’s ability to install new updates. In this case, update each Windows component with an operation such as Clean Install or Repair Install.

Damaged Windows Update component: One of the most common causes of this particular problem is a damaged Windows Update subcomponent. Several affected users in a similar scenario were able to resolve the problem by performing successive SFC and DISM scans to repair corrupted instances.

A Third-party conflict caused by Kaspersky: Of all the third-party AVs reported to have problems with IE 11, Kasperksy is the most common culprit. If you run into this problem when using Kaspersky as your default security package, you can solve the problem by uninstalling Kaspersky and removing any remnants of previous attempts to install IE 11 before reinstalling the browser cleanly.

Now that you know all the potential culprits that could be responsible for error code 9c59, here’s a list of methods that other affected users have successfully used to fix the problem.
