That looks to me like a Windows 8.3 shortened path (no spaces). Note
that these names are machine specific - there is no guarantee that
"C:\Program Files" is always "C:\\PROGRA~1".
This may be fine - what happens if you try this in explorer?

That matches your environment variable.

This is the same error as before - which to me suggests a bug in how
rpy2 is using R_HOME. I suspect its something along the lines of a
bit of code expecting a list of all the R installations found (there
could be more than one) and taking the first, but instead is taking
the first letter of the string for the only R installation.
