[Rd] Strange install key for R

One user of my batchfiles
found they did not find the R registry key because it mysteriously
was at hklm\software\wow6432Node.   The system
was a 64 bit system. I've always seen the key at
hklm\software\R-core\R which is what the batchfiles assume.
Has there been some change in where the installer puts the key
or are there situations in which the location of the key in the
registry is somehow changed?

(Note that the batchfiles do have two workarounds in case the
user cannot or wishes not to access the registry but it would
be better not to have to rely on those.)
