Has anyone installed Texlive 2018 on windows? I follow the official link to download the windows installer. But it in fact shows pictures with 2017 and is interupted by an error due to some mismatch between 2017 and 2018. How should I proceed?
Wait for another day and try again. TeXlive is distributed by a system of mirror servers and after publishing TeXlive 2018 it takes some days to sync all the mirror servers. You simply might have hit a not fully synced server.
