The forum

Microsoft killed this script: https://www.playonlinux.com/en/app-1072-POL_Install_dotnet20sp2.html , so I changed the URL to a working one. I don't know how to properly test that it works the way it is intended,and I don't know how to attach it to the sims 3 script that I am trying to make work, therefore I'm coming here and begging to please pretty please approve it so the script just works.

Thank you for the URL

Unfortunately, the URL you given is not direct ; I'm afraid it won't work from a script directly
