R help - Feb 2015 - Packages not installing on XP

I have an installation problem; on installing MethComp either from repository or
local zip file on Win XP (!) I get

Warning: unable to move temporary installation 'C:\Program
Files\R\R-3.1.2\library\filefbc44fe1354\MethComp' to ?C:\Program
Files\R\R-3.1.2\library\MethComp?
The same occurs with other packages.

The 'obvious' reason for this is that subsequent inspection shows that
there is no temporary installation at the location given.

I appreciate that R is not now tested on XP as XP is no longer supported by MS,
but since I've yet to switch to Win7+ on this otherwise serviceable small
laptop and it'll be a while before I get back to my desktops, I'd
appreciate any clues as to what - if anything - I could to do in the mean time
to get a working package install.

But R CMD INSTALL cleaned it up.

1) Check the permissions on :\Program Files\R\R-3.1.2\library, or 
perhaps better, use a separate library directory (see the rw-FAQ).

2) Switch off any anti-virus runtime checking.  There is a comment in 
the sources

                 ## Move the new package to the install lib
                 ## To avoid anti-virus interference, wait a little
                 Sys.sleep(0.5)

Thanks; that seems to have been it - probably because of a recent Norton update,
as previous package installations worked smoothly.
