This program requires a CUDA-capable video card.
No cards found.  Sorry.  Exiting.
This is currently built against CUDA 3.2 and requires at least
the version 260 drivers to work.  Try updating if you have a CUDA card.

It works fine with my 540M, which is implemented on my laptop with Optimus Technology. Can you use your nvidia card with other programs?
Also, check if you have the latest drivers installed.

What driver version do you have installed? Old drivers do not work with new binaries.

I've downloaded the 1.30 version of Cryptohaze and it works fine with my laptop

my gt540m driver version is 8.17.12.8590 with CUDA 4.1 & OpenCL 1.1
so...CUDA 4.1 is not enouth for the 1.31a version of Cryptohaze?
but this card driver was the latest version on my laptop(GateWay)'s homepage...

Built against an older version of the SDK/drivers.

That's a 285 driver version from what I can find. Right now, I'm building against 302.

Uh... options are convince me to build against an older driver (donate buttons are great for that), build it yourself (not too difficult, but probably a bit over your head), or use a Linux install with the latest driver (definitely the best option).

My laptop is just the same as yours,GT540m implemented with Optimus Technology...and it(nvidia card) works well with Diablo III ..
so..what version of driver do you got for this card?

i tried to build it myself yesterday on Backtrack5 and finally failed because i installed Backtrack5 on Vmware..when i tried "make 32bit=1",it showed "Unsupported gpu architecture 'compute_20']" and "[GRT_CUDA_device] Error 2"
so..i think i have to choose to install linux on the real machine or just build it on windows..right?

The problem with virtualization software is that the virtual machine won't have physical access to the hardware (the "hardware" on virtualization software is also virtualized). Only a natively installed linux will allow you to build Cryptohaze from source.

I'm not sure what version I have, but I know I've installed my drivers from the Nvidia website directly. This way, I'm sure I'm using the latest drivers available.
There's a feature on their website that uses java to detect your graphics card and automatically redirects you to the download page of the latest driver. I recommend that.
And in the future, try not to rely on your laptop maker's website, as it will probably not have the latest drivers available. Just my 2 cents...

Try to install the latest drivers from nVidia.com - though some laptop makers alter things such that they won't install on Windows.

VMs aren't going to work for CUDA accelerated compute.
