VSTO Outlook Add-In > Microsoft Customization Installer RRS feed

  • Question

  • Hi there, I am working on an Outlook VSTO Add-in and manage to get it deployed using InstallShield to create the relevant registry keys under HKLM. The Add-In is signed by a trusted publisher. When users open Outlook, a popup is displayed to inform that the Publisher has been verified but still prompt to "Install" or "Don't install".

    How can I get ride of this popup?

  • Hello S_G,

    This forum(Outlook for Developers) is for development issue related to Outlook Object Model and I think your issue is more related to InstallShield.

    Since InstallShield is a third-part application, so I would suggest you contact their support team for help and for current thread, I would move it to Off-Topic  thread. Thanks for understanding.

    Best Regards,

  • Funny enough, I got the same answer from Installshield :-| It's a Microsoft problem. No really helpful.

    I actually figured it out by changing the location of the Add-In installation folder from C:\Program Files to C:\Program Files (x86)\. I am still unable to explain why.
