C++ - CreateProcess failed code 2 - c++

Question

I am trying to use the CreateProcess() function in order to launch an .exe application that is in a folder in my root directory (the directory where my VS solution is). Seems simple right? It probably is but I can't for the life of me notice what I have done wrong. Every time I try to launch the .exe I get the error message "CreateProcess failed code 2" which means that the .exe file I am trying to launch cant be found.
My code:
void HavNetProfiler::LaunchClumsy()
{
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory(&si, sizeof(si));
si.cb = sizeof(si);
ZeroMemory(&pi, sizeof(pi));
// Start the child process.
if (!CreateProcess((LPCTSTR)"Clumsy\\clumsy.exe", // No module name (use command line)
NULL, // 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
&si, // Pointer to STARTUPINFO structure
&pi) // Pointer to PROCESS_INFORMATION structure
)
{
printf("CreateProcess failed (%d).\n", GetLastError());
return;
}
// Wait until child process exits.
WaitForSingleObject(pi.hProcess, INFINITE);
// Close process and thread handles.
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
}
Am I using this function wrong? Have I misunderstood how it works or have I simply missed some minor detail? I am calling the function LaunchClumsy() in a file that is placed in a different folder (that folder exists in the root folder just like the "Clumsy" folder though). Would that make a difference?
Thanks!

There are 2 immediate bugs in the code:
The LPCTSTR cast is wrong. If your code does not compile without that cast, you have passed an argument with the wrong character encoding. Change it to L"Clumsy\\clumsy.exe" to explicitly pass a wide-character string.
Using a relative path is very likely to fail. The system searches starting from the current working directory. That is a process-wide property, that can be altered by any thread, at any time. Use an absolute path instead.
