Part 1. Why Does This Error Occur?

There are many reasons why your computer might not be able to run or install Windows 11. We will talk about the most common reasons why this error occurs here. This way you have an idea of why your computer is not installing this software.

1. Your computer does not meet the requirements for Windows 11.

This is one of the main reasons your computer might not be able to install Windows 11. If your hardware does not meet current system requirements, then Windows 11 will not install. In most cases, if your computer was able to run Windows 10 then it should be able to run Windows 11.

However, if your computer is older and hasn't run recent Windows software this could be the issue. Still, older hardware isn't always the reason that your computer won't update.

2. You don't have the proper security settings enabled.

There is another system requirement that could prevent computers from fully updating with Windows 11. It has nothing to do with hardware and everything to do with security settings. Most likely, if you don't have TPM or Secure Boot enabled on your PC, you will not be able to run Windows 11.

FAQ - What Do Secure Boot and TPM Do?

TPM is found within your computer hardware. This security chip keeps your computer safe and smoothly running. This security chip has been installed in Windows-compatible computers since 2016.

This particular chip is vital in preventing attacks on your device. In particular, this tech helps to stop firmware attacks from happening. It also prevents you from using applications and software that are dangerous to your computer system.
