title: Error Message : Cannot find or open the PDB file
body: <p>I tried running sample programs provided at <a href="http://docs.nvidia.com/cuda/cuda-samples/index.html" rel="noreferrer">NVIDIA's official site</a>. Most of the programs ran smoothly except few where I get similar error messages. How can I fix that? Here's a sample of error message I got after running a program named "MatrixMul". </p>
  
  <p>Note: I have installed both x32 and x64 <a href="https://developer.nvidia.com/cuda-downloads" rel="noreferrer">NVIDIA CUDA Toolkit</a> v5.0 on my Window7x64 OS.</p>
