I had a TexLive on my W7 computer. Additionally put TexStudio. He warns that “I can't find anything, put TexLive or something else”. I want to manually set the path. How and where to do it? Set environment variables? In TexStudio in Options -> Configure TexStudio -> the Commands tab seems to be able to register some paths, but there are quite a few settings: PdfLatex, Latex, DviLatex, etc. And in texlive I found the bin folder, there are also quite a few executables. Apparently, you need to register the paths to these players, but to which ones?
Ideally, it would be nice to see a screenshot with TexStudio configured under TexLive. So that you can see in which graph the path to which particular file to register.
Or maybe it is better to reinstall texlive so TexStudio can see it normally?
