It is worth checking that the library where things were most recently installed is the first place R looks, i.e. the first entry in .libPaths(). Often R is installed by an administrator, and users can't write to the main library, so when they install packages they go somewhere else. If "somewhere else" isn't first in .libPaths(), R won't see the new installs.

I did try installing xml2 and it appeared to complete. I will ask him to try again and send me the output.

Seems like they should install the xml2 package before proceeding to load whatever (tidyverse).
This kind of "dependency missing" problem tends to be a recurring problem particularly on Windows but in general when some deeply-embedded dependency fails to load or is removed in preparation for upgrading.

Below is some output from one of my students. I have never seen this error and tried a few things (updating packages for one) but am at a loss to help further. Would appreciate suggestions that I can pass along.
Here is the error. I tried an install.packages(?xml2?) which appeared to complete but the error persists.
Error: package or namespace load failed for ?tidyverse? in library.dynam(lib, package, package.lib):
DLL ?xml2? not found: maybe not installed for this architecture?
