**I typed "installed package (car)" and it's not worked . I read the red lines and download Rtools 3.4 and they appeared like that. I read some advices on Internet anh they said thay I cant dowload the package "car.zip" on Internet and I followed but it's not worked too. It said that we can't built R version 4.0.0 but mine is 3.6.3. How can I fix this problems ? Please help me. Thanks a lot <3 **

Are you on windows ?
install.packages("car")
works fine for me.
This could mean that you are offline, or behind a proxy and cran website is not accessible.
Yes, I'm on windows. It's working now. Thank you
