I am using a custom installer action. Code found on a Microsoft site and used
as is.
Without the customer install the add-in loads on neither mahcine A nor B.

CasPol.exe -s off
When you disable CAS as described above shouldn't it take care of trust
issues?

So, Ken, I hope that somewhere in the system there is more info to be had

Usually that happens if the addin is not fully trusted on the target
machine, something that's required and usually requires a custom installer
action.

I have the same problem so let me describe it in a little more detail.

Two systems have the the Outlook Add-in installed.

One PC works fine, the other fails to load the Add-in with this text
"Load error. A runtime error occurred during loading of the COM Add-in"

Outlook add-in is failing to load when Outlook starts on some machines.

It works absolutely fine on some other machine. On problematic
machines, some times the LoadBehavior is changing from 3 to 2 when
oulook starts. I can't even find my Addin either in the Disabled list
(Help_About) or Tools-Options-Others-AdvancedOptions.
