I am only able to download the installer for 2018.
I checked out if you can download these from the SOLIDWORKS customer portal and it doesn't seem that you can, I will inform SOLIDWORKS as I would expect to be able to download from there.
You will need to request an older version download by filling out and submitting a service request to SOLIDWORKS Technical Support:
Free Product Support Request | SOLIDWORKS
See SOLIDWORKS knowledge base solution S-068152 for more info:

Make sure to accept this post as the solution if it helps so that others can benefit.
I meant to say that the eDrawings website as far as I could see doesn't allow download of previous versions either, that's why I included the link to eDrawings so you could see.
Could you please mark my response as the solution for others to benefit from?
