R help - Sep 2014 - unable to move temporary installation when install some packages

Dear expeRts,
These days? i and some of my friends often encount?? the same problem when
installing packages, e.g. when i try to install.packages("stringi"), i
will get :


package ?stringi? successfully unpacked and MD5 sums checked
Warning in install.packages :
  unable to move temporary installation ?C:\Program
Files\R\library\file28744050180\stringi? to ?C:\Program Files\R\library\stringi?

The downloaded binary packages are in
	C:\Users\po.su\AppData\Local\Temp\RtmpeobZut\downloaded_packages


But when i try to install some other packages, it is ok,like ggplot2,but my
friends encount the same problem with ggplot2 like stringi for me.
we all use windows 7, and the latest version of?Rstudio with R 3.1.1.
We investgate it, open the path dir 's modify permissions, it works for some
packages,but for packages like Rcpp, the problem still come!
Is there some one happen to  know the solution?

1) Use a less unreliable OS.

2) Tame other software running on the system.  This is most often seen 
from anti-virus or indexing software which is interfering with standard 
OS operations.
