cuda sdk not installation query

Could anybody tell me whether it is possible to install cuda 5.0 sdk alone in a system. The system I currently work seems to be having only cuda 5.0 toolkit installed, but not sdk. I dont know how it happened. I could only download a single .exe file from nvidia site for cuda 5.0. Should I uninstall current installation and re do the process in order to get cuda sdk? Is there any chance to get the display driver corrupted while re installing cuda 5.0??

It would be so generous if anybody could help me expeditiously

I assume this is Linux?

You can run the cuda 5.0 toolkit installer, and select “no” to the driver install, and “no” to the toolkit install, and “yes” to the samples - and select a local path in your own workspace if you want, to just install the samples.
