Trouble opening .stp and .step files using eDrawings Viewer 2017

Hello,

I am trying to open an .stp file, and a .step file, using eDrawings Viewer 2017.

When I attempt to open either file, I get the error message "error reading file".

My OS is Windows 10.

Any suggestions?  Thanks!

(Apologies, I am not able to post the files on this forum.  I know that others have been able to open these files, so I don't believe the files are corrupt).
