If you have bought a new computer and want to install Biblioscape on it. But you want to keep all the customized settings, import filters, styles, etc., you can simply copy your Biblioscape 7 installation folder from the old PC to the new one. Run Biblioscape on the new PC and email support@biblioscape.com for a new registration key. You will receive up to 3 keys per purchase. You will find all the option settings, customized styles and import filters are copied to the new PC. The only thing that is not copied is menu and toolbar customization. Those settings are saved under your PC's registry.
If your database folder is not under Biblioscape installation folder, you have to copy your database folder to the new PC as well. On the new PC, run Biblioscape and go to "File | Database | Open Database". Select the "*.bsl" file under the copied database folder to open it.
