The best way to install Windows 11 is by using its official ISO file that can now be downloaded from the Microsoft website itself. If you have already downloaded it and tried installing it but getting a “This PC Can’t Run Windows 11” error, you need to get rid of the appraiserres.dll file. It is basically a Compatibility Appraiser Supplemental Resources file that is required to run certain Windows apps including Windows 11. Here’s how you can replace this DLL file and install Windows 11 without any worries and errors.

  • First of all, download Windows 11 ISO file from the Microsoft website.

Method #2. Bypass TPM and SecureBoot Check

Since this method allows you to bypass the windows requirement, you would have to make a registry edit for your computer. This process is a bit risky, and you should proceed with caution. Also, make sure that you have a backup of all your personal files because there might be a chance that if you do anything wrong, you would at least have all your files safe with you. Since your device is not compatible with the new update, it won’t be able to bypass the TPM 2.0 requirement, if you update it directly. This is why let us bypass this requirement first. The steps for this are as follows:

  • Click on the Start, or press the Windows button on your keyboard.
  • Type ‘Regedit’ and click on the Registry Editor app to open it. You can also open RUN and editor the command into it.

  • Now add the following DWORD keys to this folder.


  • Open both entries and set their Value as 1.
  • Make sure that you save this registry edit, and then try to re-install the new update.

By following the above procedure you would be able to bypass the TPM 2.0 requirement, and now you just have to install Windows 11 on your device. The next thing that we are going to do is to apply a script on your Windows 11, so that this script would help you bypass the ‘Windows Insider Program’, regardless of whether your device is compatible with the update or not.
