Checksums are used to verify that the file/ application/ etc has not been tampered with from point A to point B, they are security measures.
You either have a bad disc or downloaded an iso from an unreliable source.
If you have a disc, download an iso from a reliable source and use the product key on the cd packaging for the install.
If you used an iso, download another iso from a better source.Edited by pcmonky - 8/6/13 at 7:09pm
