For reference error number 5 is access denied. Firebird writes the lock
files for a database into C:\ProgramData\firebird but it isn't able to
create the folder (you don't have enough rights).

To redirect the lock files, you need to set the environment variable
FIREBIRD_LOCK to the location where you can write.
