Does anyone have an alternate download location for this patch, because the version at this site triggers my anti-virus and is blocked from downloading.

Or, alternatively, is there another way to run Chronicles in windowed without messing with desktop colour settings?

Your antivirus falls in the false-positive-festival category (AVG, Avast, Norton/Symantec). There is nothing wrong with the file and the Heroes fans don't have the intention of wrecking your computer. Ignore the warning and get better protection.
