I'm sorry you're having trouble. I'm not a Windows user but from what 
you described it suggests that the installation only installed some of 
the files, not all of them.

Do you have a copy (maybe a screenshot) of what it said (exactly)?

Usually, when things go wrong once, they are at least consistent and go 
wrong identically every time. It sounds perverse, but replicatability is 
important for being able to find the problem

I'm afraid not, but that's because I don't use or understand Windows.

I don't think TL is updated at that kind of speed.

This is a very good suggestion. The 2019 version would also do.

Please keep us updated. I have documentation on installing TeX from the 
DVD but only for the ProTeXt application, not TeXLive, so I am 
interested to know more about installing TL under Windows.
