I had exactly this same problem with installing win 7 64 but am reporting as win 8 devel preview fault because the iso can be downloaded by you from MS. It's an odd horrible feature rather than a big fault but it caused me a lot of wasted time. Having downloaded the iso, I tried to install it. One of the things the new vm wizard asks is about the memory and the 'storage to be reported to the o/s'. The latter was set to 20G and I wrongly/foolishly thought this was too much so changed it to 6-8G. When I then proceeded with the install after a few seconds of 'windows loading files', windows came up with an error message something the effect of 'cannot load 64 bit app' because you don't have 64 bit instructions. Not true! If you don't mess with the storage setting it installs fine, but I didn't see a warning or any mention of a severe problem if one changed the 'storage to be reported to o/s, so I think this is a fault! It's a 3G download from MS so easy to try... " defect closed other VirtualBox 4.1.6 fixed Windows Windows
