No longer get minimal build to run in Internet Explore 11

Unity Engine
1

I have been able to get IE11 WebGL builds to run on unity 5.3 builds now I updated to 5.60f3 and I cant get an empty project to load in IE11 without throwing java-script error. I have tried both development build and non development build same results. Any help would be appreciated. See below for errors

In Development build I get the following error 4 times in the console and nothing ever loads
SCRIPT438: Object doesn’t support property or method ‘log2’
File: UnityLoader.js, Line: 1035, Column: 13

In Non Development build I get the following error 4 times in the console and nothing ever loads
SCRIPT5022: InvalidStateError
File: UnityLoader.js, Line: 4, Column: 8476

I really need to get minimal support for IE11 to work, Our customer is the Navy and it is beyond our control as to when they will upgrade their systems. They are typically a few version behind on everything.

Thank you

Same problem here : WebGL 5.6 Build doesn't work in IE11 ? - Unity Engine - Unity Discussions
Could someone help us ?

There is nothing specific i need from 5.6 except just being on the latest release that is all. I though 5.60f3 was the latest stable release of Unity?

Yeah I know its not really recommended by Unity but seems crazy not to test their stuff before pushing a new release. Or they should update their documentation that states IE11 is no longer a compatible solution. Really looking for an answer from someone from Unity.

About the error log2, you can add “Math.log2 = Math.log2 || function(x){return Math.log(x)*Math.LOG2E;};” in the template page before unity integration. So one error subsist, the “InvalidStateError” thing.

We upgrade to Unity 5.6 because we needed functions about Navigation (updating the nav mesh in runtime). Looking for an answer from Unity too :frowning:

I ended up down grading to 5.5 just to continue to develop. Everything works good in IE11 too. It is sad we go no support from Unity directly on this 5.6 issue

Sorry for the troubles.
We’ve logged a bug internally and will look if we can get it working again.

Disclaimer: We never supported IE11 and won’t at any point in the future.

Any progress on this bug? Just noticed that my builds are not working anymore.

It should be fixed in 5.6.1p4, however, be aware that we don’t support IE11. Therefore Unity WebGL content may or may not work on IE11.
