This error is caused by creating LeagueClientUx process in the bootstrapper
and CreateProcess failed with last error 0x5 (ERROR_ACCESS_DENIED - Access is denied).
You may have come across these reasons:
LeagueClientUx.exe has a higher file permission than your current user.
UAC is prompted when launching LeagueClientUx.exe but no permissions are granted.
Both RiotClient and LeagueClient are running with admin privileges, while rundll32.exe is not (system or AV denied).
Symlink mode (introduced in v1.1.0) should solve this problem without touching the system.
[x] Allow enable of symlink mode in the config file
