RExcel - do not work after installing new R version

When a new version of R is installed, a few things have to be done.

rcom and rscprooxy have to be installed in the new version.
 install.packages(c("rcom", "rscproxy")) 

the line
library(rcom) 
has to be added to the etc\RProfile.site (standard path Win: C:\Programme\R\R-Version\etc\)

comRegisterRegistry() has to be run (in the new version)

bin\RSetReg.exe has to be run  (path Win: C:\Programme\R\R-2.12.1\bin\i386)
