I started having this problem today (July 18, 2016) with Logos 6.
I had this problem before and finally someone at Logos pointed me a .NET Framework file that I needed to install to make it work. I tried that file today and did a repair, but still having the same problem - "Logos Bible Software Has Stopped Working," and "Noet Has Stopped Working."
This is very disconcerting that a program of this caliber would experience these kinds of problems constantly.
Why is this an ongoing problem with this software?
I have experienced this same problem since Logos 3.
