How are you starting wings?
You must have an old erlang in your path or something, this error is just strange and
indicates you environment is incorrect.

broozar, is that error happening with a fresh install of v2.1.5 or did you have replaced any of .beams files shared for fixing bugs?

[broozar]

False alarm, sorry. I uninstalled Wings, deleted the preferences.txt, and re-installed it. Now it works again.

For completeness' sake, here are the answers to your questions:
- I installed 2.1.5 into the same directory as 1.5.4 without uninstalling it first.
- It does not matter how Wings is started (Desktop shortcut, start menu, exe directly), the error is (was) the same.
- My $PATH did not contain anything looking like Erlang.
- I do not know what .beams files are

Works now though. Thanks for all your hard work on my favourite modelling software since 0.9

broozar, thanks for the feedback.

- I installed 2.1.5 into the same directory as 1.5.4 without uninstalling it first.

You definitively should not do that.

- My $PATH did not contain anything looking like Erlang.

Erland is the language used to build Wings3D. It's virtual machine (erl.exe/werl.exe) is present in "C:\Program Files\wings3d_2.1.5\bin".

- I do not know what .beams files are

The .beams files are small executables used by Erlang VM (similar to what .jar files are for Java VM)
