Dear Monks, Thanks for your reply, I really don't want to make the Sybase Open Client as a requirement and if possible bundle the required dll/obj files with my appplication. The error which I get when I bundle most of the dll's is The context allocation routine failed when it tried to load localization files!! One or more following problems may caused the failure Your sybase home directory is c:\sql10. Your sybase home directory is c:\sql10. Check the environment variable SYBASE if it is not the one you want! Check the environment variable SYBASE if it is not the one you want! Cannot access file c:\sql10\ini\objectid.dat I have bundled the objectid.dat file also in my application exe, I still get this error as well DBD_alloc method fails. Thanks, Mansi
