!!!!!!! [PERFORM THIS STEP FIRST] !!!!!!! To be able to deploy an Add-in to all users (without manually installation for each user account on a machine) you must download and install http://support.microsoft.com/kb/976811 (A 2007 Office system application does not load an add-in that is developed by using VSTO);

To enable the hotfix package, follow these steps: Go to Start menu; type regedit, and then press ENTER.Collapse this imageExpand this image Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Common\General\ On the Edit menu, point to New, and then click DWORD Value. Type EnableLocalMachineVSTO, and then press ENTER. Right-click EnableLocalMachineVSTO, and then click Modify. In the Value data box, type 1, and then click OK. Exit Registry Editor.

- For deploying an Add-in you have a couple of choices: http://msdn.microsoft.com/en-us/library/wtzawcsz.aspx (Deploying Applications and Components) – ClickOnce Deployment (http://msdn.microsoft.com/en-us/library/t71a733d.aspx) or Windows Installer Deployment (http://msdn.microsoft.com/en-us/library/2kt85ked.aspx); - You cannot use the ClickOnce approach to deploy an Add-in to all users because this method’s setup actions install the registry keys inside the active user account location (HKEY_CURRENT_User). - To be able to achieve the functionality that you desire, you must deploy your Add-in by using a MSI approach: http://msdn.microsoft.com/en-us/library/cc616991.aspx (Deploying a Visual Studio Tools for the Office System 3.0 Solution for the 2007 Microsoft Office System Using Windows Installer).

1. Open 'Visual Studio 2008'; 2. Go to 'File' > 'New' > 'Project';

3. In 'Project Types' > go to 'Visual C#' > 'Office' > '2007' and select 'Word2007 Add-in';

4. Choose a name for the project and click 'OK';

Add a ribbon and some test buttons to your Add-in (you can skip to step 5 if you do not want to perform these steps)

4.1 Right-click the Add-in project and from the context menu choose ‘Add’ then select ‘New Item…’;

4.2 In the ‘Add New Item’ window, under the ‘Templates’ section, select the ‘Ribbon (Visual Designer)’ template;

4.3 Type the desired name for the new ribbon component (for example ‘MyRibbon’), and click ‘Add’;

4.4 A visual editor appears, allowing you to customize your newly added component. Notice the ‘Toolbox’ on the right-hand side of the image below.

4.4 From the ‘Toolbox’ drag using your mouse 3 buttons, a split-button and a separator into the Ribbon tab;

4.5 You can set the properties for each visual items added at the previous step using the ‘Properties’ window. Use the ‘Label’ property to set the name of each item.

Use the ‘OfficeImageId’ to attach icons next to these elements. You have the choice of adding your custom images (on the ‘Image’ property, click ‘(none)’ and browse to a supported picture format) or using the Office built-in resources: go to http://www.microsoft.com/downloads/details.aspx?FamilyID=12b99325-93e8-4ed4-8385-74d0f7661318&displaylang=en and download the ‘Office 2007 Icons Gallery’. (To install this download: 1.Download the file by clicking the Download link (above) and saving the file to your hard disk. 2. Double-click the Office2007IconsGallery.exe program file on your hard disk to start the installation. Follow the instructions to install the file.

Instructions for use: Once you have installed this download, use Excel as you normally would. The Office Icon Gallery appears on the Developer Tab when this document is open. Note: To enable the Developer tab, click the Microsoft Office button and then click Excel Options. In the Popular section, under Top options for working with Excel, select the Show Developer tab in the Ribbon.)

Select an icon from one of the 9 the Built-in galleries and click it. A pop-up dialog box will be shown. Copy the ‘imageMso’ code into the ‘OfficeImageId’ property belonging to your object. After you build and run the Add-in project your visual elements will have that image displayed as an icon.

To add information into the drop-down visual elements (a ‘gallery’ control in our example), just click it to access its property window, and go to ‘Items’ from the list;

Click ‘(Collection)’ and the ‘DropDownItem Collection Editor’ will appear. Use the ‘Add’ button to insert new elements. You can also modify their icons just as you did at the previous steps (using ‘OfficeImageId’ property).

You can set actions for the buttons you just added.

To make your tab appear first and therefore replace ‘Home’ tab making it the first one seen by your user, click the tab from the Ribbon visual designer and go to ‘Position Type’ property. Set its value to ‘BeforeOfficeId’.

After you change ‘Position Type’ from default value, a new property will be available: ‘OfficeId’.

Select the ‘OfficeId’ property and set it to ‘TabHome’.

Caution: the built-in tab names are key sensitive. Setting the OfficeId property to TabHome value will correctly position your tab before the Home tab. If you set the OfficeId as tabHome, your new tab will be placed at the end of the built-in tabs list. Next, select the ‘ControlIdType’ property and choose ‘Custom’ from the drop-down list.

This action will make your custom tab to be displayed before ’Home’ tab.

4.6 Run the Add-in. Set it to ‘Release’ configuration, and press ‘Start Debugging’

4.7 Running the Add-in for the first time:

Make sure you set the build configuration to release 5. In the ‘Solution Explorer’, right-click the Add-in Solution and click 'Configuration Manager' to show the build configuration manager for the Visual Studio solution. 6. In the 'Configuration Manager' dialog box, for 'Active Solution Configuration', select 'Release'.

-- Adding a deployment project – 7. On the 'Visual Studio 2008'>'File' menu, expand 'Add' and click 'New Project' to add a new project.

8. In the 'Add New Project' dialog box, in the 'Project types' pane, expand Other 'Project Types' and then select 'Setup and Deployment'. 9. In the 'Templates' pane, select 'Setup Project' from the 'Visual Studio installed templates' group.

10. Type a name and click 'OK' to finish this step and create the new setup project.

-- To add the Add-in project output to the setup – 11. In the 'Solution Explorer', right-click the setup project, click 'Add' and then 'Project Output'.

12. In the 'Add Project Output Group' dialog box, confirm that the AddIn project is selected, and the 'Primary Output' option is selected. 13. Click 'OK' to add the project output to the setup project.

-- To add the deployment and application manifests – 14. In the Solution Explorer, right-click the setup project, click 'Add', and click 'File'. 15. In the 'Add Files' dialog box, navigate to the Word AddIn output directory. Usually the output directory is the 'bin\release' subfolder of the project root directory, depending on the selected build configuration. 16. Select the '[WordAddinName].vsto' and '[WordAddinName].manifest' files and click 'Open' to add these two files to the setup project.

-- Excluding Dependencies – Referencing the components that Word AddIn requires: These components must be excluded and deployed using prerequisite packages to allow them to be registered correctly. 17. To exclude the Word AddIn project dependencies, in the 'Solution Explorer', in the Word AddIn setup node, select all dependency items beneath the 'Detected Dependencies' item except for Microsoft .NET Framework. 18. Right-click the group and select ‘Properties’, change the 'Exclude' property to 'True' to exclude the dependent assemblies from the setup project. .

-- To configure dependent components as prerequisites – 19. In the 'Solution Explorer', right-click the Setup project and select 'Properties'. 20. Click 'Prerequisites' . 21. In the ‘Prerequisites’ dialog box, perform the following tasks. 22. Select 'Create setup program to install prerequisite components'. This creates the 'setup.exe' bootstrapper together with the MSI file. 23. In the 'Choose prerequisites to install' list, select the following: 'Windows Installer 3.1', '.NET Framework 3.5', '2007 Microsoft Office Primary Interop Assemblies', 'Visual Studio Tools for the Office system 3.0 Runtime'. 24. For 'Specify the install location for prerequisites', select 'Download prerequisites from the component vendor's web site’. 25. Click 'OK' to close the 'Prerequisites' dialog box.

-- Configuring the required registry keys – 26. In the 'Solution Explorer', right-click the Setup project. 27. Expand 'View', click 'Registry'.

28. In the Registry editor, expand HKEY_LOCAL_MACHINE and then Software. 29. Create the key hierarchy required for the add-in registration: HKEY_LOCAL_MACHINE\Software\Microsoft\Office\Word\Addins\SampleCompany.WordAddInName

30. Right-click the 'SampleCompany.WordAddInName' key, select 'New' and click 'String value'.
