I have tried 3 different methods (shown below) to read/write data to a memory from a game called "Growtopia" and apparently, they all fail to attach to the handle of its process. Cheat engine has no problem attaching processes to it and I am even able to modify addresses so I think there could be a solution to this.

Method 1: Using ReadWriteMemory (Python)

Code:
Code:
from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name("Growtopia.exe")


Output:
Code:
Traceback (most recent call last):
  File "C:\Users\Vincent\PycharmProjects\GrowtopiaWorldExtractor\main.py", line 5, in <module>
    process = rwm.get_process_by_name("Growtopia.exe")
  File "C:\Users\Vincent\AppData\Local\Programs\Python\Python39\lib\site-packages\ReadWriteMemory\__init__.py", line 172, in get_process_by_name
    raise ReadWriteMemoryError(f'Process "{self.process.name}" not found!')
ReadWriteMemory.ReadWriteMemoryError: Process "" not found!


Method 2: Using PyMem (Python)

Code:
Code:
import pymem

pm = pymem.Pymem('Growtopia.exe')


Output:
Code:
Traceback (most recent call last):
  File "C:\Users\Vincent\PycharmProjects\GrowtopiaWorldExtractor\main.py", line 3, in <module>
    pm = pymem.Pymem('Growtopia.exe')
  File "C:\Users\Vincent\AppData\Local\Programs\Python\Python39\lib\site-packages\pymem\__init__.py", line 44, in __init__
    self.open_process_from_name(process_name)
  File "C:\Users\Vincent\AppData\Local\Programs\Python\Python39\lib\site-packages\pymem\__init__.py", line 204, in open_process_from_name
    self.open_process_from_id(self.process_id)
  File "C:\Users\Vincent\AppData\Local\Programs\Python\Python39\lib\site-packages\pymem\__init__.py", line 226, in open_process_from_id
    raise pymem.exception.CouldNotOpenProcess(self.process_id)
pymem.exception.CouldNotOpenProcess: Could not open process: 16704

Process finished with exit code 1



Method 3: Using the Windows API (C++)

Code:
Code:
#include <iostream>
#include <windows.h>
#include <TlHelp32.h>
using namespace std;


HANDLE hProc = NULL;
DWORD pID;


bool attachProc(char* procName)
{
    PROCESSENTRY32 procEntry32;

    procEntry32.dwSize = sizeof(PROCESSENTRY32);

    auto hProcSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

    if (hProcSnap == INVALID_HANDLE_VALUE)
    {
        std::cout << "Failed to take snapshot of processes!" << std::endl;
        return false;
    }

    while (Process32Next(hProcSnap, &procEntry32))
    {
        std::cout << procEntry32.szExeFile << std::endl;

        if (!strcmp(procName, (char*)procEntry32.szExeFile))
        {
            std::cout << "Found process " << procEntry32.szExeFile << "with process ID of " << procEntry32.th32ProcessID << std::endl;
           
            hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procEntry32.th32ProcessID);
            pID = procEntry32.th32ProcessID;

            if (hProc == NULL)
            {
                std::cout << "Failed getting handle to process." << std::endl;
            }

            CloseHandle(hProcSnap);
            return true;
        }
    }
    std::cout << "Couldn't find " << procName << " in the process snapshot" << std::endl;
    CloseHandle(hProc);
    return false;
}

int main()
{
    attachProc((char*)"Growtopia.exe");

    return EXIT_SUCCESS;
}


Output:
Code:
Found process Growtopia.exe with process ID of 16704
Failed getting handle to process.

Neither running it as admin does not work, unfortunately. It works fine without a single problem with other program such as AssaultCube untill I try it with Growtopia.

Try calling GetLastError after calling OpenProcess, just add this line:
Code:
std::cout << "[" << GetLastError() << "]"<< std::endl;

after this one:
Code:
hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, procEntry32.th32ProcessID);

(And show us the output)

That's weird, 5 stand for ERROR_ACCESS_DENIED [https://docs.microsoft.com/en-us/windows/win32/debug/system-error-codes--0-499-], If you are running it as administrator it means that there is actually something that prevents you from opening that process in particular, but I don't know the game so I don't know what to tell you.

Thank you so much, giving it debug privilege and running it as admin fixed the problem! Smile
