Hi, Years that I'm using the osgeo4w installer (advanced install) with three concurrent releases minimum (ltr, current release, dev, and sometimes ltr-dev) and I can't recall on any issue I got due to this situation. And afaics there's nothing to be particularly careful of, it's just about click click click process and all got installed in the c:\osgeo4w64 folder.
Just wanted to share my experience.
