Unity Hub - Editor Installation failed : An unexpected error occured during installation

Hello.
I recently downloaded the Unity Hub application, but when I attempt to download and install any of the betas versions, the download goes fine (I guess, since downloading something is harsh with my Internet, 300 Kb/s), but when it comes to installing, it instantly shows the “Installation failed”.
In the components list, I diabled MVSC, since I already own MonoDevelop.

Hi,
Sorry to hear you are having troubles installing the editor.

Can you try installing only the editor first ?
If all goes well, could you try adding the required components after?

Thank you for your help.

I had the same issue as the op. I solved it by following your instructions but I had to close the hub application then restart it for your instructions to work and it would stop working after every component or 2 that were installed; so I had to close out of the hub app several times and repeat the process several times until everything was downloaded and installed.

Sometimes the download would fail, sometimes the install would fail and it would say, “the file was corrupted.”
I restart the hub application, add one component at a time til it breaks again, then repeat the process until all components downloaded and installed successfully.

Happening right now with my 2018 2.7f1. On windows 10 64b.

  • UnityHub 0.20.1

Also when trying to install via Unity3d installer, nothing happens after the windows admin popup.

Hello @HouseHoStudio and @HanSolar .
Can you report a bug in the Hub, please? You can now report a bug by right-clicking on the tray menu icon and selecting “Report a bug”.

Thank you

I just discovered that if you set Windows Security “Exploit protection” settings “Force randomization for images (Mandatory ASLR)” to ON, that the Unity Hub installer always fails with this error. Turning it OFF (which it is by default) fixes the issue.

Glad it helped. I was just experimenting one day, and when things started failing mysteriously, I was a little bit annoyed.

Hello, for the current version of the hub, if the machine goes off or sleep or if the internet stops during installation, the whole process is aborted. It will be fixed soon but for now, keep an eye on your computer while installing the unity editor to check for issues.

I used unity some time ago, and now im motivated to make games. I install unity hub and the intallation just stuck around 79.5-80%. I have tried a lot of thigs, even reinstall my windows and nothing helps. Even if i skip install wizard and i chose what version i want, the installation goes 100% and then gives me the same error, that i couldn`t install that version of unity. Can anyone help me? Thank you! :slight_smile:
