Hello,

I've created a .net (c#) add-in for draftsight (DS) and it works just fine on my dev machine, both in and outside of dev-environment (vs 2015).However, when I deploy it to another machine, the add-in fails to load.

The DS apparently finds the add-in configuration, because the add-in name shows up in add-ins dialog. When I select the add-in and try to load it, nothing happens. DS does not load the add-in (menu is not showing, commands are not recognized), I get no error messages from DS, nor does windows eventlog contain anything related to DS or to my add-in. 

 I've tried to install the add-in in two separate machines apart from the dev machine:

1. Windows 7 with DraftSight 2016 x64 installed.

2. Windows 10 with DraftSight 2017 x64 installed.

In both cases, the results are exactly the same.

BTW, I deploy the add-in manually at this point. So I register the dll with regasm /codebase.

My dev machine is Win 10 x64 with vs 2015.

the add-in dll is signed with certificate from comodo.

Interop dll's referenced by my add-in are version 2016.3.0.4050. This version is also the same that I find in machines where I tried to deploy (in APISDK/tlb). 

At this point I am pretty much clueless and have no idea of what might be the problem. So, I'd really appreciate any help or pointers toward solving this issue.

Regards
