How to fix CLR error: 80004005 The program will now terminate in Windows?

Issue: Hi, I am getting CLR error: 80004005 The program will now terminate when I try running Discord and some other programs on my Windows 10 PC. It is pretty annoying, as my other computer runs all the programs I am having trouble with completely fine. Are any fixes available for this?

Solved Answer

CLR error: 80004005 on Windows is a fatal error that terminates the application that is being run and prevents it from starting. The issue can also occur when trying to install new applications. While the problem is relatively old and dates back to Windows XP times, those who run the newest Windows versions still encounter it from time to time.

According to many user reports on various support forums,[1] they were unable to run one, some, or all programs due to the error, which reads the following:

Update.exe – Fatal error

CLR error: 80004005.
The program will not terminate

As the error message explains, the app simply fails to launch due to the fatal error. Without a doubt, this can be a very frustrating experience, especially when several apps are affected. Thus, trying to fix CLR error: 80004005 The program will now terminate can be critical.

In most cases, the root cause of the error lies within .NET Framework. According to Microsoft, “Each version of .NET Framework contains the common language runtime (CLR), the base class libraries, and other managed libraries.”[2]

Some sources reported that multiple versions of the NET Framework might be causing the CLR (Common Language Runtime) error, and uninstalling them could help fix the issue. However, for a very long time now, Microsoft is shipping the framework along with Windows updates, which then becomes embedded within the system. This results in users' inability to uninstall .NET Framework in a regular way via the Programs and Features section.

How to fix CLR error: 80004005 The program will now terminate in Windows?

There are suggestions to download third-party apps that would help you remove the framework, but it is not recommended at all. In fact, .NET Framework was designed in a way that Windows would support multiple versions of it running at the same time without conflicts,[3] and you likely have several of them running right now. Therefore, there is no need even to try uninstalling them.

Instead, the reason for CLR error: 80004005 The program will now terminate is likely to be caused by the app itself, as it is trying to run .NET Framework incorrectly. Therefore, in order to mitigate the issue, you have to fix the installation of the app, fix .NET Framework, or provide sufficient permissions for the app in question. You can find the step-by-step solution below.
