I downloaded and installed the MonetDB 4.12.0 with SQL 2.12.0 from SourceForge using the link on the MonetDB website. http://prdownloads.sourceforge.net/monetdb/MonetDB-Installer-4.12.0.msi? download I installed it without error but when I try to start the database with sql_server I get the following error: C:\MonetDB>msqlserver.bat # Monet Database Server V4.12.0 # Copyright (c) 1993-2006, CWI.

I know this isn't the best platform to run MonetDB on but it will be a couple of weeks before I can free up a linux server so any help would be appreciated. Thanks. Jim Foley
