Cuda GeForce GT 630M

Sorry for my english, it isn’t my language.


I need some help, please: I have an ASUS PC, i7, GeForce GT 630M graphic card, win 7, 64 bits.
I need to use the software “DaVinci Resolve” but for this, I need cuda.
I tried to download cuda for notebook, win 7, 64 bits but it doesn’t work.
My antivirus, Avast, blocks some element, it’s a problem ?

What can I do ?
