Programming software help

[Sgt Wild Lion]

Im trying to install some programming software 'visual.net' i think its called, but for some reason it wont install. My laptop keeps saying that there is a program stopping the program from installing, i then reboot the system but the same error keeps coming out. In order to get it to install, ive gotten rid of all programs that i dont need such as limewire and others but the program still wont install. some help pls!

My laptop is a Fujitsu LifeBook S-Series running Windows XP professional and using centrino duo processors if that might help.
