This means that some other program (often a video driver) rudely changed the
floating point control word, but that R caught the change and stopped it. From
R's point of view the problem was prevented. Now, it is possible that the
other program thinks the floating point control word is still set the way it
wants, in which case it might have problems with numerical accuracy. R should
be ok, though.

If the MD5 hashes agree then the files are the same as when the installer was
built. There is negligible probability that a change in the file will leave
the MD5 hash the same.
