Building and deploying an Outlook 2010 Add-in (part 2 of 2)

  • Artykuł

In the first part of this series, we went through the steps to create a simple Outlook 2010 add-in, how to build a custom ribbon, and finally the backstage area. But what use is your add-in unless other people can use it too? In part 2, we will look at the steps to create a setup package so that you can distribute your add-in to others.

Setup Project

Returning to the solution you started in part 1, you will now need to add a Setup Project. I’ll call mine “SetupMyOutlookAddIn”. When the project has loaded in, Visual Studio will bring up the File System screen of your Setup Project. We will need to make a few changes here:

  • Select Application Folder, and open the Properties window (you will probably find it easier to have the properties window open the whole time – we will be using it a lot!)
  • In the Properties window, under DefaultLocation, change [ProgramFilesFolder][Manufacturer]\[ProductName] to [AppDataFolder][Manufacturer]\[ProductName]
  • Now, right click Application Folder – Add – Project Output… and on the dialog that appears, choose “Primary Output”.

We’ve now effectively told the setup project to install all our application goodness to the user’s AppData folder (Normally C:\Users\[username]\AppData in Windows 7, for example). We are doing this as this is a safe, sandboxed location that requires a minimum of privileges to install to. Here’s roughly how your screen should look now…

FileSystem_25D70833

Now, we need to remove some of the .dll files that were added as Primary Output (because we do not need them). In Solution Explorer:

  • Expand ‘Detected Dependencies’ in your Setup Project.
  • Right click and ‘Exclude’ everything under this folder except for:
    • Microsoft.NET Framework
    • Microsoft.Office.Tools.Common.v4.0.Utilities.dll
    • Microsoft.Office.Tools.Outlook.v4.0.Utilities.dll

There are now 2 files you need to reference explicitly in your setup project. These are files that are created when you build your solution – so you will need to point to the release folder. You may use debug if you wish – just remember you are pointing there. For production software, you should point to release. So, in the File System window of your setup project:

  • Right-click the Application folder and select Add – File…
  • Browse to your application folder, and then bin\Release
  • Select the .dll.manifest, and .vsto files that reside there.

Your File System window should now look something like this:

FileSystem2_17988F43

Registry

To get our add-in working, we will need to add registry keys. When you are developing the solution in Visual Studio, this happens automatically in the background, so it can be a surprise that you will need to do it explicitly! The keys we are creating will be saved to: HKCU\Software\Microsoft\Office\Outlook\Addins.

Open the Registry Panel in your Setup Project, then:

  • Expand the HKEY_CURRENT_USER key, then Software, and rename [Manufacturer] to Microsoft (because we are adding this key to the Microsoft Office section of the Registry).
  • Create a tree of key values underneath Microsoft: Office\Outlook\Addins
  • Finally, create a key for your add-in. Give it a unique name, such that it is different from the add-in project name (so you can identify keys created by the installer, and keys created by Visual Studio).
  • In that key, set the following values:
    • String – “Description”
    • String – “FriendlyName”
    • String – “Manifest” – set this to “[TARGETDIR]MyOutlookAddIn.vsto|vstolocal”
    • DWORD – “LoadBehavior” – set this to “3”
  • Select your new key (the one you just set values for) and in the Properties window, set DeleteAtUninstall to be true (important: do not set it for any keys higher up in the tree!)

Here’s how your Registry screen should now look:

Registry_17988F43

Prerequisites

Now, we need to make sure that the Setup.exe you produce will check for prerequisites on the client system. This can be done by:

  • Right-click your add-in project (not your setup project) and select properties
  • Ensure the following are ticked:
    • Microsoft .NET Framework 4 Client Profile (x86 and x64)
    • Microsoft Visual Studio 2010 Tools for Office Runtine (x86 and x64)

Prerequisites_17988F43 

Finishing Touches

We’re pretty much done! A few things you may want to change:

  • Open the properties panel of your setup project and update the values there such as Version and Product Name.
  • Open the User Interface editor of your setup project, and delete the Installation Folder screen. This will stop users from installing the add-in to a different location (that may stop your add-in from running).

Build your add-in, and then right-click your Setup Project and select Install. The next time you open Outlook, you should be prompted to allow your new add-in to run!

    Mukunda it looks like you are targeting VSTO 3. You may find more information about this problem here: social.msdn.microsoft.com/.../543a9f63-908e-4292-b30a-cff07e4b6709

    Dinesh: Have you set the "Copy to Output directory" value of the xml file, and ensured that it appears in the file system/application folder of the Setup Project (you can put it there manually if not)? The other thing you could do is put the connection information in the project settings, so these will be shipped in the app.config automatically for you. Matt

    Hi, thanks for this great step-by-step tutorial. I have followed it with interest, and written my first Outlook COM-AddIn. My only problem is: after running the MSI file on another machine (not the dev machine), I have to double-click the .VSTO file in the installation directory to get the AddIn in Outlook. Any ideas? Best wishes Michael

    Michael, check registry settings. The "Manifest" value should be a path to your vsto file

    i'm facing the same problem. tried out everything. running the setup won't make the add-in load in outlook. only running the vsto works! I have outlook 2010 64 bit on windows 7 64 bit and in my setup I've set the target platform as x64.

    First, thanks for the tutorial it was extremely helpful.  Second and this goes out to anyone who may know the answer.  basically I have created an additional form region and added it to the appointment/meeting class.  Everything works as expected however, if I send a meeting to users and then look in my personal sent items the additional form field is not there.  It does appear if I pull up the appointment in the calendar though.  I am thinking that it may be that the calendar appointment and the sent appointment are stemming from 2 different classes one being appointment and the other being mail but I was hoping to get some diffinitive insight into the matter.  If it is because they stem from 2 different classes can the new form data be passed to the sent item object? Any information anyone is willing to share would be greatly appreciated as I seem to be unable to find an answer via Google. Thanks, Dave

    Hi, its nice article. Can any body suggest to suppress the security message having options "Install" and "Don't Install". Moreover when I install setup its name is shown in install/uninstall list. When I run outlook first time, it install addin if i press "install" option and my addin project name becomes also visible in install/uninstall list. Is it normal behaviour. Futher when i uninstall the addin setup, setup name is removed from install/uninstall list but my addin project name remains there and i have to remove it manually by right click and uninstall option.

    Thanks very much for this tutorial. I was able to deploy an Outlook add-in successfully and have it automatically loaded by registry settings managed by GPO.  So all good on that side of things! However, I'm confused on how to deploy an update to the add-in. I can see that running the initial install of the MSI deploys the manifest and vsto files to the application directory (C:Program Filesblah), then our registry changes force the vsto to be installed for the current user when they next start Outlook.  All good. If I then update the add-in and associated setup project, including all of the version numbers, the new MSI can successfully deploy the new manifest and vsto files to the same application directory but the user's add-in will not automatically update to use the new files, instead it will continue to run the old version of the add-in. It appears that the vsto has to be first manually uninstalled by the user (they may see a duplicate of the add-in name in their Programs and Features control panel that they can uninstall even if they're not local admin). After that the registry settings will again force the updated manifest and vsto files to be installed. I just don't know why this bit isn't automatic when it sees the vsto and manifest files with higher version number in the application directory. I can probably run the automatic uninstall through a logon script but just wondering if I am missing something? Cheers

    excellent article! very complete and useful. Thank's However some things are missing or problematic: 1 ◦ String - "Manifest" - set this to "[TARGETDIR] MyOutlookAddIn.vsto | vstolocal" the corect value is: file :///[TARGETDIR]MyOutlookAddIn.vsto|vstolocal to avoid errors with vs2010

  1. The following key HKCUSoftwareMicrosoftOfficeOutlookAddinsMyOutlookAddIn works locally, not with Terminal Server or Citrix. For Terminal Server and Citrix, it is necessary to add the following key: HKLMSoftwareMicrosoftOfficeOutlookAddinsMyOutlookAddIn. In Terminal Server x64 with Office 2010 x86, this is enough. 3 in a mixed environment (Windows x64 and Office x86) and Citrix, Outlook plugin does not appear without the following key: HKLMSoftwareWow6432NodeMicrosoftOfficeOutlookAddinsMyOutlookAddIn obviously, all the key value must be present (Description, FriendlyName, Manifest and LoadBehavior) for each registry key
