Hi Patrick,

no I didn't try to compile & start the examples. I just downloaded the
CUDA driver from Nvidia & didn't get any examples.
I downgraded the driver to 3.1.17 now (used to have 3.2.17, the latest
from Nvidia for the 9600M GT).

However, still the same: CUDAResourcesInstall[] immediately gives a
$Failed as result and I can't manage to get the CUDA resources
installed manually:


evaluation of In[7]:= Message::name: Message name CUDAResources paclet
path `1` is not valid. is not of the form symbol::name or
symbol::name::language. >>
Out[7]= $Failed

As mentioned I just renamed the downloaded file, which came in as to .paclet .

Still clueless,
