[R] R-2.4.0 and MS Vista OS - installing packages

[Charles Annis, P.E.]

I have installed Microsoft Vista Release Candidate 1, and R-2.4.0, on a 4
year old DELL box with a 2.26 GHz P4 and 1 gig.  It was a clean install – R
is the only non-MS program running.

I cannot install packages from CRAN, nor from local zipped files.  (I have
R-2.4.0 installed on a Windows XP machine and have had no problems so the
difficulty seems to be Vista not R, however they aren't playing together
nicely as they should.)  

The CRAN installation of R-2.4.0 on the Vista machine was without incident,
but after downloading the zipped packages from CRAN I get this error
message:


> utils:::menuInstallPkgs()

Error in zip.unpack(pkg, tmpDir) : cannot open file 'C:/Program
Files/R/R-2.4.0/library/file6fc97ac2/RColorBrewer/chtml/RColorBrewer.chm'

Any help would be appreciated.  Thanks.
