Firebird: Access Denied
By default you are not allowed - by Windows - to create files into the C:\ drive root, except when running as Administrator. Make sure you create a folder and create the database file there. Also note that it is customary (but not required) to give Firebird databases the extension .fdb.

Also make sure that C:\Remake does not already exist as a folder (directory), see also https://stackoverflow.com/questions/42280679/firebird-permission-denied
