Help requested with installing the CUDA environment

Hey everyone. 

 I'm stepping up from Fedora to RHEL6.2 and I really appreciate the solid foundation of RHEL6

 I am also unsure of how to go about doing some things.

 I am following the https://access.redhat.com/knowledge/solutions/64300 inorder to install this CUDA so I can begin to learn about programming with the graphics card.

 I followed along and have hit a snag.  Perhaps there is a simple thing to do but I will do much better asking those in the know.

At this point something is wrong and I am not sure what to do.

 /tmp/NVIDIA*.run --kernel-source-path /usr/src/kernels/`rpm -qa kernel --queryformat "%{PROVIDEVERSION}.%{ARCH}\n" | tail -1` --no-questions --ui=none --no-questions --accept-license
bash: /tmp/NVIDIA-Linux-x86_64-275.19.run: Permission denied
 

 This is the install parrt of the "Nvidia Download and install Nvidia Graphics drivers:"

 I appreciate the help.
