Error on install

[burton89 0]

When I try to install, it gets to about 78% and it says "An I/O error occurred while installing a file. This is normally caused by bad installation media or a corrupt installation file.", and gives the option to retry (which doesn't work) or exit. How to fix?

Have you tried a fresh download of the install file? Maybe your previous download has a CRC error.
