Hey man, did you ever figure this out? Cuz I've been having the same problem running the same specs.
I have booted the launcher AS AN ADMINISTRATOR (figured I'd make that clear so I'm not treated like I'm 5.) My taskbar will disappear for a moment and my cursor will spin blue as if it's going to work, and then it doesn't. The taskbar reappears and nothing happens.
First and foremost, I am running Windows 10 on a 64bit OS. I have the most up to date C+++ Redist from Microsoft. I have redownloaded the files and re-extracted them several times. I've hit a wall.
I've read through the forum several times in an attempt to not be slaughtered the way some of the other guys did, but I'm just at a loss. This all seems really cool, I've been all over Clone Hero for months now and I've been looking for a solid way to get this back. Please let me know if someone comes up with something. Thanks.
