Since uninstalling and reinstalling did not work I thought maybe my laptop was corrupted. So it was time to do indepth system maintenance.
So I cleaned my registry files, spyware, tracks, temp files etc several times. No dice. I then defragged my registry and hard drive. That took many hours, to no avail. Then I tried a deep antivirus scan. Again many hours but no success.
Then I tried something counterintuitive. All previous successful installs were done while the antivirus was enabled. I disabled antivirus and reinstalled FTM2012 from disk. Ta da! Trial and error persistence worked. Back to research.
