Description
EA login fails with a "program not found" error every time login is attempted, both in the KYBER Launcher GUI and via kyber_cli.exe get_token. The Maxima data folder remains completely empty, suggesting Maxima never successfully completes initialization.
Steps To Reproduce
Install KYBER Launcher on a non-C: drive (e.g. F:\Program Files (x86)\KYBER Launcher)
Open the KYBER Launcher
Click "Login with EA"
Complete EA sign-in in the browser
See "program not found" error with stack backtrace
Expected Behavior
EA login completes successfully and the KYBER Launcher reaches the main screen.

Additional Context
The launcher log shows: [WARN] [maxima] - invalid stored client path, fixing... followed immediately by SEVERE - [maxima] - Error logging in: - AnyhowException(program not found)
The Maxima data folder at %AppData%\ArmchairDevelopers\Maxima\data is completely empty, indicating Maxima never writes its config
EA App is correctly installed at C:\Program Files\Electronic Arts\EA Desktop\EADesktop.exe (confirmed via registry)
The kyber:// protocol handler registry entry exists under HKEY_CLASSES_ROOT\kyber
Issue persists after full uninstall including AppData deletion, Defender exclusions, and running as administrator
