The error message typically indicates a corrupt or structurally mismatched installation media , an antivirus program blocking the setup file , or a damaged ISO file generated during a Windows upgrade or clean install .

This is a protective measure; the operating system would rather fail to boot than load a compromised kernel module. However, this strictness turns a simple installation attempt into a forensic puzzle for the user.
