Hi, I have a key to install Solidworks SEK 2019-2020 through my university and I enter the https://www.solidworks.com/support/community-download#no-back to download the software. I make sure to select the 2019-2020 edition, however, when I start installation it keeps bringing me to the Solidworks 2020 edition and states that my serial key is invalid for this edition. 

How can I get the 2019-2020 version?
