Why xiloader closes immediately after "Connected":
The FFXi.dll COM registration must have ThreadingModel = "Apartment" in the registry. Running regsvr32 on the DLL doesn't set this value - it must be added manually or via the fix_registry.ps1 script.
Registry paths that matter:
HKLM\SOFTWARE\WOW6432Node\Classes\CLSID\{989D790D-6236-11D4-80E9-00105A81E890}\InprocServer32
(Default) = C:\path\to\FFXi.dll
ThreadingModel = Apartment ← CRITICAL
- LandSandBoat - FFXI server emulator
- xiloader - Boot loader for private servers
