bash - W8 Registry issue? Calling shell script from within C++ app but no arguments get passed -


i have c++ program uses system() call execute , send arguments shell script. worked fine on windows 8.1 computer. i'm trying run same thing on new windows 8.1 laptop. shell script gets executed no arguments received.

the c++ code

system(("c:/script.sh file.png &").c_str());

in shell script verify number of arguments received. 

#!/bin/bash echo "received arguments:  $# "

i can execute , pass arguments script manually git bash 

$ sh script.sh file.png  received arguments: 1

but if system() call within c++, received arguments 0. same exact code works on other machine. problem seems related windows registry. first time ran c++ program on new laptop, windows asked me program should use execute shell script. selected powershell. yet caused powershell open/close in frenzy , had restart computer. went explorer , associated .sh opened git bash. executing script within c++ program works, safe passing of arguments.

is possible registry setting somehow prohibit passing of data?

windows registry .sh scripts

consider calling system("/path/to/bash c:/script.sh file.png &") make life easier os, otherwise needs launch program suggested in shebang.
