    I FINNALY DID IT!!11!! I, basically uninstalled unity hub in task manager and everything then I restarted my pc, then I downloaded the hub (the one for returning users) Than i visited the download archive and following code prod's tutorial I downloaded version of 2019 3.1 (2019.3.1f1). I unchecked every add on except for documentation. Then i added everything else after downloading the original one.

    So I just tried setting up the Unity Hub. Would like to share a few pointers:

    • Installing the latest version of Unity just kept failing after many attempts (despite restarting Unity Hub, Updating Mac, Reinstalling Xcode, Restarting Mac, selecting some or no modules etc and different combinations), with no errors and just a message “Something went wrong“ (Very helpful Unity!).

    • I tried different versions, not just the latest, Official releases 2018, 2019 and 2020 as well as 2020 LTS (latest), but none would install.

    • Eventually, I manually Installed Visual Studio for Mac first (outside of Unity Hub).

    • Unity Hub was able to detect VS for Mac now and was not suggesting to install it when selecting Modules. But installing latest version would still fail!

    • Only 2018 installed first (finally some progress) but latest would still fail.

    • Eventually, only installing the versions in sequence from oldest to latest worked, i.e first 2018, then 2019, then 2020 official release and then 2020 LTS.

    • I did not select any modules during installation of the Unity versions. So I added Android and iOS Build Support modules only after all versions were installed.

    I found that you can download the file directly if, when trying to download from the hub and you are quick, it gives you a URL when it reports an error. You can grab that url quickly just by pressing F12 and screen-capturing it. By typing that url into a download manager (like IDM) you can download the file directly.

    The URL is of form:
    https://download.unity3d.com/download_unity/<hashcode>/Windows64EditorInstaller/UnitySetup-2020.<ver>.exe

    Substitute the <hashcode> with whatever hex appears in your screenshot, and <ver> with whichever version you want to install.

    I assume you could use firefox/chrome/whatever to grab the file directly, I only suggest IDM for download resumption.

    I'm having the same problem. Also I went to the temp folder where Unity stores installation files (C:\Users\*user*\AppData\Local\Temp\unityhub-*RandomCharacters*) and when I try to open the UnitySetup64-2020.3.2f1.exe file I get this error

    NSIS Error
    Installer integrity check has failed. Common causes include incomplete download and damaged media.
    Contact the installer's author to obtain a new copy.

    Just crashed into this as well. For me, this feels like a Windows issue. But can't identify what. Hub 2.3.4 working perfectly until yesterday when I went to upgrade to 2019.4.25f1. It then won't update anything with the messages that everyone has posted. Tried everything suggested, but nothing works. The only way back for me (as by now I had no Unity versions on the Windows 10 box) was to use UnityHub to do the download and then manually install.

    The laptop next to me still working on Windows Pro with the latest updates on, main dev PC with Windows Home latest updates failing.

    Unity Hub downloads everything and sticks what you need in

    C:\Users\username\AppData\Local\Temp\unityhub-xxxxxxxxxxxxxxxxxx

    before it notes the failure

    You can run everything from there and then point UnityHub back at it. UnityHub doesn't give you the modules option, but it at least works. It becomes slightly more complex if you want additional modules loaded, but it's workable to get back up and running.

    I am trying to load Unity3D editor from Unity Hub. It seems to download, then fails to instal. Was there an issue with Apple Silcion?

    I have similar problems with Unity 2021.1.10 on Win 10.
    To resolve the problem, I cleaned up the Editor folder (Program Files\2021.1.10f1), downloaded the installer from the following archive https://unity3d.com/get-unity/download/archive , installed it, and restarted Unity Hub.

    There was a similar issue with Unity 2021.1.9 on Mac. In that case, I downloaded it from the archive, installed it, but there I had to give rights on some folders, and afterward, Unity could work properly.

    I had to change my path from unity on my c drive and routed it to my secondary drive and it worked. Obviously not everyone has a second drive but thought I'd share.

    I am using the 3.0 hub and after I finally managed to download the application (2019.4.30f1) but its not installing at all. I am on Windows 10, Is there any settings I need to change to have Windows accept the installation?

    I had a problem: On my mac, when I try to download, it said: Editor application: Install failed: Validation failed. How can I fix that?
