  1. Using Edge on Server 2022 the HCW application won’t run at all.

    I even manunally enabled ClickOnce Support via the Edge Flags. Going to https://aka.ms/HybridWizard displays the Open this file? dialog but clicking open does absolutely nothing.

    I downloaded the HCW .application file and went through changing the default application to open it (it was already set to ClickOnce but I changed it anyway) still no result.

    I was able to install it on a 2019 server. Our 2 Exchange Servers are on server 2022, but is it ok to run the HCW from a 3rd party server (same domain of course) when wanting to go Classic Full Hybrid?

  2. We followed all that steps, but is still not possible to open the HCW:

    – on server 1, nothing happens after we confirmed the question in then edge to open the HCW
    – on server 2, HCW was downloaded, we sat “open with” to the click once – and when trying to open the downloaded HCW, again nothing happens …
    – on server 3, there happens nothing when we paste the link in the browser.
    We tried it with Edge and with the IE, three different servers, but in the same network (Server 2016, server 2019).

    1. We solved it by installing Microsoft Edge (via Microsoft Edge, btw) – after the “new installation” (over an existing Edge that has done well some weeks ago!) everything went well.

  4. Thank you! Installing edge got our HCW up and running.

  5. Thank you for this. Once again you have succeeded where Microsoft has utterly failed in their documentation. They are only one of the richest companies on earth so I can see why they spend no money on properly explaining their constantly problematic software. In any case, Thank God there are people like you willing to help.

  13. Mate, thank you so much. As we know hybrid mode makes the migration so much easier. I was starting to think I would need to use a third party to do the migration until I saw instructions. Thanks again.

  14. I tried this and it will not work either.
    Keep getting “Cannot download the application. The application is missing the required files”

    1. I followed the steps on a new Windows Server 2016/2019/2022. The application started after entering the HybridWizard URL in Microsoft Edge.

      Use the browser Microsoft Edge. If it’s another browser, ensure that you enable ClickOnce support.
