Installing Solidworks 2019-2020 From the Solidworks Website
If you already have an old version of Solidworks installed on your computer, you must fully uninstall it before installing Solidworks 2019-2020
You will need about 18 GB free drive space to install Solidworks. This can be slimmed down slightly by declining to install help manuals and sample files if you're really low on space.
In a web browser, open http://www.solidworks.com/SEK
On the first line ("I already have a Serial Number that starts with 9020:") select "Yes".
Select "2019-2020" from the Version dropdown.
Enter your email address and select "Student Team" from the last dropdown, then click "Request Download".
Scroll down and accept the license agreement.
On the next page, click the button that says "Download".
Download the self-extracting archive and unzip it. When it is done, the Solidworks installer will open.
If you get any warnings about pending updates, read the message carefully and follow the instructions. Usually, the installer asks you to quit and restart your computer. After you have restarted, follow these steps again, and you should not get a popup.
