Well, first, you need to establish exactly what runtime error is occuring during the load. &nbsp;Do you have try-catch logic in the add-in intialization (probably an event called OnLoad or OnInitialize) that will send reports of errors to the application error log? &nbsp;That would be my first step.

Have you by any chance got sample code (vb.net) of a VERY basic outlook add-in that only displays a menu, and does something stupid like msgbox &quot;hello&quot; when you click on it?

Hi Experts, <br />
<br />
I've written a vb.net outlook 2003 add-in in vs2008, but after i installed it on the client machine, it fails to load. <br />
I can see the Add-in in outlook under COM Add-Ins, but it's not active and the error message that goes with it is: <br />
<br />
Not loaded. A runtime error occurred during the loading of the COM Add-In.<br />
<br />
I've read up SO much on articles suggesting that it's a CAS security problem, but i don't really know where or how to fix this? <br />
<br />
Can anyone PLEASE assist me in this??? It's extremely urgent.... <br />
<br />
Thanx!<br />

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
