What's The Deal With Scar?

First off whenever I DL the newest version of scar (3.22) and install it, it all goes fine until I try to run it, the actual scar executable itself disappears. I'm guessing this is my anti-virus removing it, but I'm not sure and my anti doesn't show any log or reports of doing so.

Despite that I have the old 3.12 version of scar, which works fine aside from not downloading SRL or any other includes, it just gives some error, probably because it's an old version of scar?

Now I know you can get SRL separately, but is it even worth it? I haven't checked up on the SRL's home site that deeply but is SRL even still alive? Does it work with the new rs layout, randoms, etc?

Thanks
