GPU computing sdk installation error

Hi all
I am using Dell laptop NVS 4200M with an i7 CPU and OS windows 7. I have been trying to install the GPU computing sdk to get started with writing a software. When I started the installation process, I got an error on my screen saying:
"Setup has experienced a problem
Please do the following
-Close any running program
-Empty your temporary folder
-Check your internet connection
Then try to run Setup again
Error code: -6005
The screenshot of the error is attached below:

I tried the above mentioned all three options and also rebooted my system many times but unfortunately the problem could not be solved.
Can anyone please help me in solving the problem? I'll be really obliged.
Waiting for your replies
Kind regards
Jennifer
