Trying to export then import existing VM - "encountered error during import operation"

Hello,

I'm very new to Hyper-V and have had the task of "cloning" an existing VM we have in use.  From the Hyper-V management console, I have successfully (i think) exported the VM that I want to replicate, but then receive the following unhelpful error message when walking through the 'Import Virtual Machine' wizard.. 

"Hyper-V encountered an error during import operation"

I receive this after walking through the entire wizard, selecting the VM to import (the one I exported), and selecting destinations for the new VM files.

Any help is greatly appreciated as this is a critical business and time sensitive issue for me.

Environment is Windows 2012 R2
