Thanks, gentlemen, for your suggestions. @WoodyZ, the checksums match. @a.p., I'm frustrated with Acer, because they have hidden lots of features from the BIOS pages. VT-x and XD are not options available in the BIOS settings. Based on a Google search, I looked in Computer -> Properties -> Advanced System Settings -> Advanced (tab) -> Performance (settings button) -> Data Execution Prevention. It tells me that my processor is DEP capable and DEP is enabled.
Sorry, I should have been more specific about the symptoms of my problem. The install went fine, no errors, but the only player executable I get is in Program Files (x86) and won't load a 64-bit iso.
