"The given path's format is not supported" when passing argument to any cmdlet

May 20, 2013 at 10:28 PM
built and installed powertools cmdlets - can see them in powershell. However, every time I try to run one (in this case Confirm-OpenXmlValid ./test.docx):

Confirm-OpenXmlValid : The given path's format is not supported.

Is there something I'm missing?
