I'm the developer of Textractor (google it and you'll find the GitHub page with more info, I can't post links) trying to make it work with as many games as I can. The first thing Textractor does is inject a dll into the game process with this code:

[code]if (AutoHandle<> process = OpenProcess(PROCESS_ALL_ACCESS, FALSE, processId))
{
#ifdef _WIN64
BOOL invalidProcess = FALSE;
IsWow64Process(process, &invalidProcess);
if (invalidProcess) return AddConsoleOutput(NEED_32_BIT);
#endif
static std::wstring location = Util::GetModuleFilename(LoadLibraryExW(ITH_DLL, nullptr, DONT_RESOLVE_DLL_REFERENCES)).value();
if (LPVOID remoteData = VirtualAllocEx(process, nullptr, (location.size() + 1) * sizeof(wchar_t), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE))
{
WriteProcessMemory(process, remoteData, location.c_str(), (location.size() + 1) * sizeof(wchar_t), nullptr);
if (AutoHandle<> thread = CreateRemoteThread(process, nullptr, 0, (LPTHREAD_START_ROUTINE)LoadLibraryW, remoteData, 0, nullptr)) WaitForSingleObject(thread, INFINITE);
else if (GetLastError() == ERROR_ACCESS_DENIED) AddConsoleOutput(NEED_64_BIT);
VirtualFreeEx(process, remoteData, 0, MEM_RELEASE);
return;
}
}

AddConsoleOutput(INJECT_FAILED);[/code]

The problem is that in the game I'm trying to add support for VirtualAllocEx returns null i.e. it failed, and checking the last error code it is 5 (ACCESS_DENIED). The official MS documentation for VirtualAllocEx doesn't say how this could happen, and I've never seen it fail like this before. Presumably it's a result of the antihacking software used by the game. I get the same result (ACCESS_DENIED last error) if I remove VirtualAllocEx and try WriteProcessMemory or CreateRemoteThread with addresses I know should be valid. I've tried setting SeDebugPrivilege and I also tried using the native API (NtAllocateVirtualMemory) and all of that failed.

So what to do next? I'd like to try CE's custom functions for opening process and writing its memory, but the antihack detects CE. So, could someone point me to the source where those are implemented? And is there anything else I should try?

adjust process token and token privilege.

I tried that too, didn't work.

ensure you are logged using admin account, and make sure to run your executable as admin.

add this manifest to your resource, also save it as .xml:

I was always running the executable as admin.

sorry i cant help you, as i never experienced such issues. (just a tip: do a quick revision maybe you are missing something)

Based on the game name you gave, will say that it's due to the anti-cheat.

As for that as well, we do not assist with online/multiplayer hacking on this site.
