    Hi, hope you're doing well.

    We're trying to install IIS CORS module via Web Platform Installer.

    Here's the command:

    webpicmd.exe /Install /Products:"CORS 1.0" /AcceptEula

    For a while it worked well, but starting last Friday (January 15th 2021), we are getting this error:

    Downloaded file failed signature verification and may have been tampered with

    Are there any changed been made for this file? We cannot understand the issue.

    Thanks a lot for your help.

    We are also getting the same error. This error occurs with both manually running the web platform installer, and using the command line mentioned above.

    Hi aliaksanderkazlou,

    Downloaded file failed signature verification and may have been tampered with

    This problem should be caused by system compatibility. The default version installed by Web Platform Installer (WebPI) is x86 installer, you can try to install x64 installer.

    Best regards,

    I have tried the x64 installer... it appears to run but CORS still not installed. I think there is still an issue with the installer.
