I have a copy of the 2016 SOLIDWORKS Essentials manual in my hands. I want to access the ebook so I can read off the computer.
There is a serial number on the inside cover of the book. I tried "registering" the book by typing this serial number into the "register a product" page linked through the SolidWorks customer portal after logging into my account. Unfortunately I get an error saying the serial number is too long, and that it should be between 16-24 characters.
How do I access my ebook using the serial number I have?
