today i updated my display driver to 266.58, and then all my projects of OpenCl can not work, give such error infoimation at line:
cxGPUContext = clCreateContextFromType(0, CL_DEVICE_TYPE_GPU, NULL, NULL, &ciErrNum);
Error -32 CL_INVALID_PLATFORM
I think that the OpenCl driver cannot support my GTS250 card.
Unfortunately, i have lost my last driver setup file and forgot the name of last driver(maybe 190.62)
I download all the release drivers from 190.62 to 266.58 which GTS250 and XP system supported, and no one cannot works well!
I try all the driver the whole day, it is too strange!
Anybody can tell me the solution, thank you!
My card is GTS250, operation system is XP.
