Pluggin won't launch

[FranckS]

Just purchased a license, installed and it won't launch when trying to activate pluggin:

// Error: line 1: Unable to dynamically load : E:/Unwrella Maya/Maya2016x64/plug-ins/Unwrella.mll
The specified module could not be found.

I tried both this custom and default install directories, same problem.

I'm with Maya 2016 SP6 64bits, under Windows 10 Pro.
