Serial number of the eDrawings professional should be your key.
OR is the serial number for SOLIDWORKS Professional/Premium version?
Thanks for the reply deepak.
To answer your question serial number is edrawing professional stand alone.
This problem has been solved.
License key or authorization code for activation of edrawing professional stand alone need to request from solidworks, VAR should file service request.
Yes the serial key for eDrawings has very little use to the end user- the very long (100+ digit) authorisation key is required to be read into the Help menu. You VAR needs to request this as for some reason SW do not update their systems yer to year to refresh this
