I've been trying for weeks. The closest thing I can do to installing is finding the ".iss" file type (which Windows does not know how to open), of which I forgot the name of it. There is no .exe anywhere.
Also, to confirm, this supports GPT/GUID on Windows, correct? And is it so simple that a grandma could do it, or do you need to know command lines and programming stuff to encrypt or decrypt a full disk/OS? All I want is a simple, easy-to-use (GUI based), open source, free program that can encrypt a UEFI GPT/GUID drive. I've been searching for YEARS. Thank you.
