The Metasploit OpcodeDB is offline. The current database is missing most newer operatings systems and nearly all language packs, making it somewhat useless for exploit development today. Once we update the database and build a new front-end, the database will be brought back online. In the meantime, we recommend that you extract files as needed from the public Service Pack download files (using a cab extractor) and then process these with msfpescan.
