Unable to get outlook com addin to install correctly michael.porfirio[ at ]people.net.au 3/14/2006 6:55:36 AM Hi, I'm a very new to Visual Basic .Net and are having some issues with a com add-in that I built. I'm using Visual Studio 2005 and have built a simple com add-in that creates a command bar with a button. When this button is clicked it launches a custom appointment form. When I build the project from within Visual Studio, it builds with no errors and when outlook is restarted the command bar appears and works exactly the way I want it. Now, if I create an msi / setup.exe from within Visual Studio from the project and then use it to install the button on the same computer, the com add-in no longer appears. If you look under com add-ins in outlook it's there, but it's unticked. If you try to tick the box you get the following error: "Not loaded. A runtime error occurred during the loading of the COM Add-in." I have also look under Help/About/Disabled Items and there are no disabled items listed. When you run setup.exe it puts all the files under c:\ProgramFiles\request. I've checked the registry differences between when I simply build the project and when I run setup.exe. The entries look the same except for the manifest location when I run setup because it now points to the new location. Can anyone help me? I need to get this button deployed across my company asap and I've gotten to the end of my limited knowledge of com add-in programming.

Re: Unable to get outlook com addin to install correctly "Dave Kane [MVP - Outlook]" <dkane[ at ]mvps.org> 3/15/2006 6:01:41 PM It sounds like the issue is .NET Code Access Security. I'm guessing that you built using Visual Studio Tools for Office (VSTO), which automatically grants access to your assembly when you build it (using the full path), so it runs/debugs with no problem from the build location. But your install puts the assembly in a different location and the previously granted trust no longer applies. If this is the case then you need to modify your setup project to grant full trust to the installed assembly. This article http://msdn2.microsoft.com/en-us/library/s66ay8f7(VS.80).aspx discusses one method of doing that. Look for "Code Access Security Policy" Sue Mosher page on VSTO (http://www.outlookcode.com/vsto/index.htm) has a list of articles on deployment. The two by Mads Nissen cover a different way to have the MSI run an action that grants trust to your assembly. <michael.porfirio[ at ]people.net.au> wrote in message news:1142314180.716077.4500[ at ]e56g2000cwe.googlegroups.com...
