Thread: running .exe file with CreateProcess

so im trying for a couple of days to run a simple .exe file (that creating a simple text file) using the function createprocess. i put the path that i want to run, in the cmd, as the second input for the function. the debugger says that the function succeed but the txt file does not apear anywhere. how can i know whats been happening?
i tried so many things like using TCHAR and backslashes for the path but none solved it.
i can add my thread function code if someone would like to observe it.

Code:

 DWORD WINAPI thread_function(LPVOID lpParam) 
{
	TCHAR *t;
	int command_line_out = 100;
	tests_line *test = (tests_line*)lpParam;
	char command_line[MAX_LINE_LEN];
	TCHAR *fixed_exe_line[MAX_LINE_LEN];
	//connect_file_name_and_args(test, &command_line); // creating the command line "text1.exe hello"
	//printf("\n%s\n", command_line);
	*fixed_exe_line = _T("\"C:\\Users\\sagic\\Desktop\\Example1 test1.exe\" hello");
	STARTUPINFO start_info ;
	PROCESS_INFORMATION process_info ;
	ZeroMemory(&start_info, sizeof(STARTUPINFO));
	ZeroMemory(&process_info, sizeof(PROCESS_INFORMATION));
	DWORD wait_code;
	if( !CreateProcess(NULL,fixed_exe_line , NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS, NULL, NULL, &start_info, &process_info))
	{
		printf("%d", GetLastError());
		printf("create process failed");
		return ERROR;
	}
	
	wait_code = WaitForSingleObject(process_info.hProcess,INFINITE);

	if (WAIT_OBJECT_0 != wait_code)
	{
		printf("Error when waiting\n");
		return ERROR;
	}
	CloseHandle(process_info.hThread);
	CloseHandle(process_info.hProcess);
}

i want to add that if i run the process outside the thread function it does run test1.exe.
