Visual C++ 2008 installation error 1603

[alexanderthegreat]

I recieve an error when I try to install Visual C++ 2008( from Feb 2009 Digit DVD). The error code is stated to be 1603.

Now the problem: The installation stops as soon as it starts the first step (Runtime Pre-requisites). I recieve an error report message. On checking the contents, I deduced that the error code I recieve is (Can you believe my luck!!!) 1603. I know it just means "Fatal Error During Installation".
Someone please help me!
Here are the 3 setup logs:-
