a problem about Identity Center

hi expert,

It's my first time to install Identity Center database on MS SQL Server. I open a command prompt and navigate to SQL-server directory,then run mxmc-install.cmd . I'm prompted for some passwords.then there is an error information:'osql' is not recognized as an internal or external command,operable program or batch file.

and there no information in mxmc_logfile.log

thanks a million.

Best regard,
