Cannot install web GL module on macs (install failed: Installer encountered an error )

Unity Engine

Anyone else having a problem installing the WebGL modules? I tried on my Mac pro 10.8.5 and imac running 10.11 and both times, using the Download Assistant to install only the WebGL module , the install fails and I have no Web GL module loaded.

Which version of Unity ? Could you please try again to see if you consistently get this problem ?

I was on an older (5.3.2?) version, upgrading to 5.3.4 now… and i now am able to load WebGL although last night I wasn’t able to see this new version for whatever reason. Thanks!

I had the same problem on OSX.
In my case the solution was to make sure that the correct version was installed below /Applications/Unity !
I am currently running both Unity 4.7 and Unity 5.4 and in my case Unity was setup as a symlink to 4.7.
WebGL installed w.o. any problems once it was the 5.4 version that was below /Applications/Unity
(WebGL installs stuff below /Applications/Unity/PlaybackEngines/WebGLSupport)
Hope this can help someone :wink:
Cheers,
/Thomas

shreegj,

I was running into the same problem as you. The issue for me was that I had renamed the Unity folder (as recommended by a class I’m taking) from “Unity” to “Unity 5.4.2”. By renaming it back to “Unity”, the WebGL installer was able to run successfully.

Hope that helps.

Hi all,
I facing the same issue, I’m using Unity 2018.2.0f2 with Unity Hub.
Installation failed every time I tried. I thought it was because I had older versions installed so moved them to an other folder but it doesn’t change anything !

@[Marco-Trivellato]( Cannot install web GL module on macs (install failed: Installer encountered an error ) members/marco-trivellato.341252/) have you an option that doesn’t force me to reinstall everything or an other version of Unity ?

Thx
Alex

I can’t reproduce the issues with installing you are seeing. Can you be so nice to reproduce the issue again on your machine and then send a bug reporter from the hub so we get the logs for it.

For any future install issues with the hub please refer to the dedicated Unity Hub forum at Unity Engine - Unity Discussions

I managed to install the component using Unity HUB. The problem is with the direct link from the Editor.

Now that I’m looking closer at the situation I can see the WebGl Support under PlayBackEngines in the unity folder.
For some reason the Build settings window is reporting that “No WebGl Module Loaded.” I’m a bit new to this was wondering if I should move the WebGl support to another location so that Unity see’s it? It will not allow me to select the “Build” as a result.

Unity 2019.1.11
Same Error. Can’t install Web GL module. Downloads fine, but installation fails during the “Validating Files” section.

I faced this problem as well. If you are using a Mac, you can try this:

  1. go to “Application”
  2. create a folder named “Unity”
  3. drag all the stuff under the current version of Unity that you are using into the new “Unity” folder
  4. install the module
  5. drag all the stuff back to the original folder
  6. DONE
    I’ve tried this for a few times and it worked pretty well.

Go to ‘Installs’ → Select a version (click on the 3 dot menu) → Add Modules → WebGL Build Support
Installing through the hub also did the trick for me.

Oh hell yes thank you, going through the hub worked easy for me. Tried everything else on this page, but it was mostly outdated.
