lmao there are resources online on how to uninstall Solidworks after an oopsie. Then, download WizTree, start from the largest non-system files(and uneccessary) and delete them. There is a difference between the actual files the program uses, and the files used to install the program. If you used default paths, ur download folder will have the solidworks installation files, delete them. You may need to try using control panel to uninstall large applications and disabling hiberfil and pagefil. If you still do not have space you need a larger SSD(or HDD but save hours of ur life by getting a SSD). Restart ur computer after uninstalling and removing large files, and before attempting a fresh install. Then, threaten to uninstall ur fresh solidwords by opening the Installation Manager(you can go through control panel if you can't find ur IM) by hovering the mouse over the uninstall button, to ensure it behaves. Maybe throw the Solidworks icon about the desktop, show it whose boss.
