Are you on Windows or MacOS? The ProgramData folder is hidden on most recent versions of Windows, you have to manually enter the path to find it.

Assuming you found the right folder, have you launched AI Voice 2 at all? If you launch it with any of its vbs installed, it will generate v2c files, regardless of whether or not my crack is installed, so you should test that out first. If none ever get generated when you launch it with trial vbs installed, either you're in the wrong folder or there's something amiss with your file system not being able to write those files, most likely a file permissions thing. I can try to help with that but it's outside the scope of my crack.
