I am new to Compiere. I installed it following the usual way but I noticed that there was an error when I tried to drop and create a new database.  I tried running the setup again but for me to get back to the part of adding and dropping a db, I have to reinstall. I want to know whether it's possible to install the sql files that compiere uses manually from any source.
