Fail to Install

My Computer, A brand new Laptop running Windows 7 and if the brand is important it is a Compaq. If I could remember the model I'd tell you that too, tells me this

"The feaure you are trying to use is on a network resource that is unavailable. Click okay to try again or enter an alternate path to a folder containing the installation package 'sins_setup.msi' in the box below."

Then it gives a type line with the browse button next to it.

I tell it to install in Program files x86 where every other game I've put on this computer goes perfectly but this one refuses any location I submit. I have no idea what I'm supposed to do and help with this issue would be wonderful. I really don't want to learn that I wasted my money. Thanks
