    bvenhaus Thank you for your question. We removed the ms-appinstaller custom scheme due to a security vulnerability. We do intend to bring this back, and are working on it. For now, you can update the link on your website by removing 'ms-appinstaller:?source='

Aditi_Narvekar Could you provide us any additional information on this?  This has serious implications on how we distribute certain apps.

 

Can you at least confirm at least if it will eventually be restored?  I understand if you cannot provide a timeline yet but we would like to know so we can plan accordingly.  I would hate to go through the trouble of implementing an alternative (albeit less effective) approach only to have it restored shortly afterwards.

 

Thanks.

Ernie

    I've now opened a business support ticket on this from my company's support contract and set it to Sev-A, Critical Impact. I'll post here if I get traction.

      Hi all,
      To confirm, yes, we do plan on correcting this. I know the team is working on bringing it back, but don't have a date for this yet.

        Thanks for the update Aditi! We have had a critical issue open with Microsoft premiere support for over a week, and unfortunatly have gotten nowhere except links to articles about workarounds, so at least your responding here. At this point we are having to figure out ways around this issue and abandon this funtionality (probably for good). It is a shame though as it worked very well for quite a while.
