Hi you have made a regression as I have both an Nvidia card and ATI 5850 on Windows 7 and with latest drivers CAL examples don't work if have enable ATI and Nvidia GPUs.. previously it was working at least I can run CAL and CUDA programs side by side.. if I disable in device manager (without reboot) nvidia gpu,  cal samples start to work..

The problem is yours as Nvidia CUDA works with ATI GPUs installed and also CAL samples were working previously..

The error seems to be in

 

C:\Windows\System32\atigktxx.dll

as Visual studio debugging shows:

 

 

 



'oclDeviceQuery.exe': Loaded 'C:\Windows\System32\atigktxx.dll', Cannot find or open the PDB file
