I have Live Helper Chat (LHC) installed on a fresh Windows Server 2022 Standard box, but the application throws a “Permission denied” error every time it tries to write to its cache directory. I double-checked the NTFS permissions on the target folder and everything looks correct, so the fault may lie with the service or IIS/PHP user that the chatbot is running under—I’m honestly not certain. I need someone who understands LHC on Windows, IIS/PHP file-system security, and standard Windows Server troubleshooting to step in, find the exact cause, and make the cache fully writable so the chatbot runs without errors. Deliverables • Pinpoint the root cause of the “Permission denied” message. • Apply the proper fix—whether that’s adjusting service credentials, tweaking IIS/PHP settings, or correcting an overlooked folder permission. • Prove the solution by showing LHC running normally until successful install If you know Live Helper Chat and Windows file-security quirks, this should be a quick win.
