Outlook Add In & InstallShield RRS feed

  • Question

  • Morning all :)

    I have just completed an Outlook add in, and used InstallShield to create the setup file.

    However, I just passed it on to a colleague, and it seems to install ok, but the add in does not appear in Outlook?

    Any ideas? Would it be better to go down the ClickOnce route?

  • This could be to do with the Registry Entry, is there a guide to setting this up?

  • Hello Darryl,

    First of all, I'd suggest checking out the windows registry keys. See Registry Entries for Application-Level Add-Ins for more information. 

    Also Microsoft Office applications can disable add-ins that behave unexpectedly. If an application does not load your add-in, the application might have hard disabled or soft disabled your add-in.

    Hard disabling can occur when an add-in causes the application to close unexpectedly. It might also occur on your development computer if you stop the debugger while the Startup event handler in your add-in is executing.

    Soft disabling can occur when an add-in produces an error that does not cause the application to unexpectedly close. For example, an application might soft disable an add-in if it throws an unhandled exception while the Startup event handler is executing.

    When you re-enable a soft-disabled add-in, the application immediately attempts to load the add-in. If the problem that initially caused the application to soft disable the add-in has not been fixed, the application will soft disable the add-in again. Read more about that in the How to: Re-enable an Add-in That Has Been Disabled article

    Finally, make sure that you did all the steps described in the Deploying an Office Solution by Using Windows Installer article.

  • Thanks for that :)

    One last thing - if doing "Rebuild Soulution" will that rebuild the setup file as well?

  • It depends on what projects were chosen for building in Visual Studio. By default, if you don't change anything all projects are rebuilt when you use the Rebuilt solution option.

  • Were you able to find the cause of the issue? Could you share it for other forum readers?

  • Just trying it out now. Two articles seem to contradict for 64-bit machines.

    Root\Software\Wow6432Node\Microsoft\Office\application name\Addins\add-in

    The other says


    So do I need to add it the Wow6432Node bit?

  • Did you have a chance to check out the VSTO - Deploy an Office Add-in by using Windows Installer sample project which support the x64 platform as well?

  • I sorted it all. It was the registry entry issue. I hadn't set it up correctly.

    Thanks for all the quick replies (Y) :) much appreciated.
