Hello Carmelo,
The call stack above includes a reference to a thread and this thread may be the cause of the issue as all the object models in Office are *not* thread-safe: you should call any Office object model on the main thread only.

Hello Andrei,
Ok, in this specific case the routine is started by a timer but in other cases this issue happened in routines started on the main thread. Anyway, I don't understand why the issue shows up just in few machines and not in all of them. |

There's no easy explanation to some things. There's no explanation at all to this issue; or, I don't know it. But in my practice I saw TYPE_E_LIBNOTREGISTERED generated by accessing the IRibbonExtensibility COM interface from a background thread. So, switch to using You should use System.Windows.Forms.Timer as it fires its event in the main thread.
