Warning message - plugin for Trueimage 2015-14-13-12

During a test of the Trueimage 2015-14-... plugin, I obtain the following warning message:

(Macro_Library.script) Can not copy file iernonce.dll

I know a warning is not an error, yet I would like to know if I really can ignore it, ot it is better to fix it. 
I attach the log...
Thanks, P

iernonce.dll must exist on your source.

use official source when using project.
