Unity 5 RC2 Build to WebGL Fails

Hi there,

I'm unable to build my project to WebGL and get the following errors:

Error building Player: Exception: /Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper2/UnusedBytecodeStripper2.exe did not run properly!

Any ideas on why this is happening?

 

I have no input on the error itself, but as the error is with the bytecode stripper, you may still be able to complete your build using other stripping options, or disabling stripping entirely.

 

How do I disable stripping?

 

In Build Settings, press Player Settings...
Then, under the Other Settings tab, you should have have:
Stripping Level* (right under Optimization).

Set this to Disabled and test.

 

I looked at the stripping level, and it's already disabled. Still getting the same errors.
