"sp2-0667 message file sp2 lang .msb not found and sp2-0750 error is coming on windows"

Earlier it was working fine i think some path issue is there so can any one tell me how to resolve the issue or how to set the path on windows machine

• have you checked ORACLE_HOME environment variable is set properly? I think the errors SP2-0667 and SP2-0750 are caused by ORACLE_HOME is not set correctly. Jan 6 '16 at 5:07
• pls tell me how to set through command prompt

• C:>Set ORACLE_HOME=path to oracle home Jan 6 '16 at 5:16

Setting the ORACLE_HOME environment variable incorrectly may cause these errors.

On Linux, you can set ORACLE_HOME as \$ export ORACLE_HOME=path\to\oracle\home and on Windows you can set as C:\>set ORACLE_HOME=/path/to/oracle/home/.
