Could not load assembly OpenXmlPowerTools A strongly-named assembly is required.

I am getting this error at runtime when I open the form where I am reading a word document using OpenXML:
Could not load file or assembly OpenXmlPowerTools or one of its dependencies. A strongly-named assembly is required.

I have to sign the assembly for my project, this is a requirement.
But when I uncheck "Sign the assembly", then my app works fine, and I can process the word file.

Anyone knows how to fix this problem? do I have to sign OpenXmlPowerTools ? how?

This relates to C#, but might also apply to your question: https://stackoverflow.com/questions/...ly-is-required

I don't know much about this, but hopefully my link is of use. :-)
