I do not know how to download solidworks 2019 and I cannot open 2019 files currently. Can I upgrade to 2019 version without repurchasing?
I suspect by the post title that you have an Education version of SOLIDWORKS.
SOLIDWORKS 2018-2019 Education is based on the 2018 SP2 commercial release.
You will need to wait for SOLIDWORKS 2019-2020 Education and talk to your education reseller about if you have to re-purchase. It depends.
