Rustclient.exe Unknown software exception (0xc000001d)

I cant play Rust, im always getting this Message: unknown software exception (0xc000001d) found in 0x3f8a94f7. I have windows 7 and Ati Radeon HD 5700
Can anyone help me?

Try to start it one more time, I’m sure it’s gonna work

It does not work. Anyone know how to fix it ?
