R 3.3.0 is not a released version of R. It appears that you have obtained a
version of lme4 that is ahead of its time. This would have been a perfect time
for you to have followed the Posting Guide mentioned below (in particular the
inclusion of complete version information such as the sessionInfo function would
provide). If you obtained your lme4 through CRAN, the maintainers made a
mistake. If you found it somewhere else then you are the one who erred. Since
it loads fine for me my bet is on your mistake.
