ImgDrive This operating system is not supported

Because of Microsoft's annoying code signing mechanism, starting with version 1.9.0, ImgDrive only supports Windows 11, Windows 10 and Windows 7 which had installed the SHA-2 update support patches.

You can upgrade your operating system to Windows 11/10/7 to use the latest version of ImgDrive, or install the old version of ImgDrive 1.8.7:
