I was able to successfully install 64-Bit Windows 7 Professional last night!
Since my last failed attempt I wiped the hard drive using Darik's Boot and Nuke which appears to use a DoD Short method. I'm skeptical as to whether this really contributed to anything given that I had previously used Acronis to do a wipe of the hard drive.
The other thing I did was download a new ISO... 64-Bit Windows 7 Professional SP1-U. Given that I had previous tried 4 different 64-Bit Windows 7 ISOs that I had, I don't think it was the ISO itself. Rather, my guess is that SP1-U has something that resolved the install conflict. If I'm not mistaken, SP1-U contains some kind of hotfix that pertains to install problem.
Or, maybe it was just dumb luck? Whatever the case, given that it's installed, I'm not planning to spend any more time trying to figure out what exactly it was. Thanks for all who contributed with help!
