I am trying to install SW 2021, provided by my university. However, it keeps crashing early on during install. I think I was able to remove most of the files from SW 2020, but I am still having problems. 

Previously, I tried to uninstall SW 2020 but the uninstaller window opened but was blank. So, I probably made a horrible mistake, when I then manually deleted every SW file or folder. I am afraid that has made uninstalling even more difficult. My university's IT support tried but was unsuccessful. 

Please see the following error messages and error log files. Please help! Thank you!
