Dear Bioconductor Support,

i recently tried to upgrade my R version to the newest R version 3.2 in one of my computers in order to check how it works:

My current info is : sessionInfo()

R version 3.1.1 (2014-07-10)
Platform: x86_64-w64-mingw32/x64 (64-bit)

locale:
[1] LC_COLLATE=Greek_Greece.1253  LC_CTYPE=Greek_Greece.1253    LC_MONETARY=Greek_Greece.1253
[4] LC_NUMERIC=C                  LC_TIME=Greek_Greece.1253    

attached base packages:
[1] tools     stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] installr_0.15.3

I followed the code: 

install.packages("installr"); library(installr)

updateR()

and although R was installed, with some questions ask about copying the old packages in the new version and upgrade them, finally there was the following error:

updateR()
Installing the newest version of R,
 please wait for the installer file to be download and executed.
 Be sure to click 'next' as needed...

The file was downloaded succesfully into:

Running the installer now...

We can not seem to find the location if the new R you have installed.
The rest of the updating process is aborted, please take care to copy
your packages to the new R installation.
[1] TRUE
Warning message:
In install.R(to_checkMD5sums = to_checkMD5sums, keep_install_file = keep_install_file,  :
  There was some problem with installing R.  Some files are not what they should be (e.g: check MD5 sums did not pass all the tests). 
  You can try installing R again (either manually or through install.R()), 
  and if the problem persists you can file a bug report by running:  bug.report(package = 'installr') 

I also tried through istall.R but the same error remains. Any directions or help ?
