After the Windows 11 build leaked, people rushed to download the ISO on Virtual Machines and PCs. While most of them succeeded in installing the same, some were left with a TPM 2.0 error. If you’re one of them, let’s look at how you can bypass this error and start using Windows 11.

TPM stands for Trusted Platform Module for starters, which provides additional hardware-based security built inside the processor. By trying to install Windows 11 on a computer without TPM 2.0, you’ll get the following error “This PC can’t run Windows 11. The PC must support TPM 2.0.” You might not get this error if you have a PC with Intel’s 4th gen or above processor, but if you don’t, here’s a process that you can try to solve the error.

Replace The appraiserres.dll File

1. Head over to this link and download the appraiserres.dll file. This file is from a Windows 10 ISO. Since Windows 10 doesn’t check if a computer has a TPM 2.0 chip, we essentially replace this file with the one in Windows 11.

2. If you’re on Windows, mount the Windows 11 ISO (Right-click on the ISO and click on Mount). If you’re on Linux, open the ISO using an archive manager.

3. After mounting/extracting, head inside the extracted ISO and go to the sources folder.

4. Find the appraiserres.dll file and delete it. Copy the appraiserres.dll file that you downloaded and paste it into the Windows 11 ISO.
