Hi,
We use listener add in to open Office Word that has Word add in.
As of yesterday, after win 7 update kb4022206, we suddenly recive the following exeption:

Assembly Full Name: mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
Assembly Version: 4.0.0.0

Exception Source:

Exception Message: Unable to create specified ActiveX control.

---- Stack Trace ----
System.RuntimeType.ForwardCallToInvokeMember(memberName As String, flags As BindingFlags, target As Object, aWrapperTypes As Int32[], msgData As MessageData&)

Hello Zipi,

This exception is a result of a problem (exception?) that occurs when Add-in Express creates an instance of the UserControl specified as a custom task pane (in the TaskPanes collection of the add-in module).

I suggest that you debug the constructor of the UserControl as well as initializers of the variables declared on the class level of the task pane class. I recommended not to have such initializers at all; initialize class-level variables in an event of the UserControl e.g. Load.

Regards from Belarus (GMT+3),
