You really need to discuss this with the package maintainer (as the 
posting guide asked).

But there are several 'optimization' packages on CRAN which do have 
Windows' binary versions that would therefore be easier to use.

To do so, I tried to install the package Rcplex on my computer (Windows7-64), so I did the same as installation Instructions<http://www.geeklog.net/docs/english/install.html> and edited the file "Makevars.win" by adding the path "C:/Program Files/IBM/ILOG/CPLEX_Studio_Preview124/cplex/include" (where the trial version of cplex has been installed on my computer) to the lines "PKG_CPPFLAGS=-I<CPLEX_DIR>/include" and
> "PKG_LIBS=-L<CPLEX_DIR>/lib/x86_windows_vs2008/stat_mda -lcplex111 -lm". Then, I just tried to install the package as usual by R with the command "install.packages" but there is an error as following
