The command in the system() API's argument should include the path of the executable to be launched from the system() API. For example: Say there is an executable sample.exe (executables are put in c:\sys\bin on the hardware). So, the system() command should be system("c:\sys\bin\sample.exe") . Normally, the same code is expected to work on the emulator as well, in which case make a folder bin in \epoc32\release\winscw\c\sys and place the executable at that location before execution.

MACRO_LONG_LONG_SUPPORTED should be added by to the mmp file to get the support of long long related APIs.
