Problem loading winbugs into R

I'm trying to run a code in the R that loads the winbugs package I already have installed

require(R2WinBUGS);

But I'm having this error

    Error in file(con, "rb") : cannot open the connection
    In addition: Warning message:
    In file(con, "rb") :
      cannot open file 'c:/Program Files/WinBUGS14//System/Rsrc/Registry.odc': No such file or directory
    Error in bugs.run(n.burnin, bugs.directory, WINE = WINE, useWINE = useWINE,  : 
      WinBUGS executable does not exist in c:/Program Files/WinBUGS14/
    Called from: bugs.run(n.burnin, bugs.directory, WINE = WINE, useWINE = useWINE, 
        newWINE = newWINE, WINEPATH = WINEPATH)

I have already changed the working directory . I'm using windows 10 and tried unsuccessfully to install winbugs.

EDIT: I was able to run my code after installing WinBugs14, it ran normal, but that appeared here
