aspnet_regsql not working at all

I would like to create the ASP.NET User database template on a database of my own, because I'd like to fully untegrate the user system with the rest of my DB. As I've read, i needed to use the aspnet_regsql tool. I put all the options (because my database is running on SQLEXPRESS and is in an mdf file in my project's folder). the program starts and seemingly runs without any errors, however, when I open 开发者_JS百科the database after that, not tables or stored procedures have been added.

One more thing: I did one more test. I intentionally gave the -d option a wrong mdf file address, and surprisingly, the program "finished" correctly, yet no file was crated or modified whatsoever.

The question was resolved. Please, see my own comment on the first one
