You are getting this error because you are not giving full path   C  Users    file exe  If you want to remove this error then either give full path or copy that application  you want to open  to the folder where your project  exe  is present saved    include  lt windows h gt  using namespace std  int main       system   start C   Users  Folder  chrome exe https   www stackoverflow com      for opening stackoverflow through google chrome   if chorme exe is in that folder     return 0

Provide the full path of the file openfile exe and remember not to put forward slash   in the path such as  c  users username etc     instead of that use  c   Users  username etc  for windows   May be this will help you

You should always avoid using system   because   It is resource heavy   It defeats security -- you don t know you it s a valid command or does the same thing on every system  you could even start up programs you didn t intend to start up  The danger is that when you directly execute a program  it gets the same privileges as your program -- meaning that if  for example  you are running as system administrator then the malicious program you just inadvertently executed is also running as system administrator  If that doesn t scare you silly  check your pulse  Anti virus programs hate it  your program could get flagged as a virus    You should use CreateProcess     You can use Createprocess   to just start up an  exe and creating a new process for it  The application will run independent from the calling application   Here s an example I used in one of my projects    include  lt windows h gt   VOID startup LPCTSTR lpApplicationName          additional information    STARTUPINFO si          PROCESS INFORMATION pi         set the size of the structures    ZeroMemory   amp si  sizeof si        si cb   sizeof si      ZeroMemory   amp pi  sizeof pi           start the program up   CreateProcess  lpApplicationName       the path     argv 1             Command line     NULL               Process handle not inheritable     NULL               Thread handle not inheritable     FALSE              Set handle inheritance to FALSE     0                  No creation flags     NULL               Use parent s environment block     NULL               Use parent s starting directory       amp si                Pointer to STARTUPINFO structure      amp pi                Pointer to PROCESS INFORMATION structure  removed extra parentheses                Close process and thread handles       CloseHandle  pi hProcess        CloseHandle  pi hThread        EDIT  The error you are getting is because you need to specify the path of the  exe file not just the name  Openfile exe probably doesn t exist
