When installing HCC3 on Dot Net Nuke 9.1 It works well, but I get TWO .dll, one dotnetnuke and the other is HCC-CMS-related. I assume this is why HCC3 works on Dot Net Nuke 9.1. I put hudge amount of efforts to understand all the pieces and why HCC3 works on Dot Net Nuke 9.1. But really I need more information about the major (infrastructure related) decisions: maybe a graph of all the related components!

Let me know how I can help, I would love to take a stab at it as well.

Have you had much experience with Hotcakes Commerce? Say like 1.x or 2.x?
