I placed this post on the wrong forum, so I will try it again here: I am running Logos Bible Software 4.6c SR-4 (4.63.0.0384) on an HP Envy dv4 Notebook running 64-bit Windows 8 version 6.2.9200 build 9200. I have had great frustration the past 36 hours with a perpetual notice that Logos is preparing my library. I have gone to Task Manager and ended the process only to have it pop up again when I tried to load Logos. The solution I was offered was to download a free Logos 5.2 engine and I did that, but when I try to run it, I get no response. My computer tells me (apparently since it is a 32-bit program) that it is incompatible with my operating system. I was told on the other forum that this should not be a problem.
