Walter, While that answer is correct, the better answer would be for the Project to modify engine and installer to be Windows Vista+ compliant and have all configuration files stored in All Users\Application Data\Firebird and not in Programs Files\Firebird

You can install Firebird in C:\FIREBIRD\ or something so and no problems writing to any of its files. Greetings. Walter.

I don´t remember exactly the details, but this is still working. What I did was the following: When my application initiates, it checks if there exists a database named MYAPPLICATIONCONFIGURACION.FDB. If it doesn't exist, it creates it. When the application creates the database, it creates 3 UDFs executing SQLs begining with "DECLARE EXTERNAL FUNCTION ..." The UDFs are the following (the names are in spanish): MMudfUbicacionDelAlias It is called with a parameter "Alias". It opens the file aliases.conf, look for the alias and returns a string with the path of the database. MMudfPudeEstablecerAlias It is called with a parameter "Alias" and a parameter "Path". It opens the file aliases.conf, and adds a new line with Alias=Path. MMudfPudeCrearDirectorio It is called with a parameter "Directory". It creates a folder in the hard disk with the name indicated. In the file aliases.conf, there is a line MYAPPLICATIONCONFIGURACION = C:\...\MYAPPLICATIONCONFIGURACION.FDB. When a user wants to create a new database, the application opens the database MYAPPLICATIONCONFIGURACION and executes the following SQL: SELECT MMudfPudeEstablecerAlias('Alias','Path') FROM RDB$DATABASE This can be done using the application in the server or in any client PC of the newtork. Regards Eduardo Thanks Eduardo. I would never have thought of going this way, not good with FireBird procedural coding. Like I wrote to Stefan above I found a different way to go about this. I took a copy of the Aliases.conf to a temp folder and updated it as necessary. Then I used ShellExecute Windows API with "runas" parameter to run a custom batch file that does the replace of the Alias.conf file with the updated one in the temp folder. That brings up the UAC prompt but that is fine I don't mind announcing that to the user of a system change. Kind regards Bhavbhuti
