"Use the shell and utilities, Luke!" - prefixed echo to setup.exe for demo:

$ echo setup.exe -P `echo a,b,c`
setup.exe -P a,b,c
$ echo setup.exe -P $(echo a,b,c)
setup.exe -P a,b,c
$ echo a,b,c | xargs echo setup.exe -P
setup.exe -P a,b,c
$ cat file
a
b
c
$ paste -d, -s file | xargs echo setup.exe -P
setup.exe -P a,b,c

$ man dash
$ man bash
$ cygstart /usr/share/doc/bash/html/bash.html
$ cygstart /usr/share/doc/bash/html/bashref.html
$ man xargs
