title: SP2-1503: Unable to initialize Oracle call interface SP2-0152: ORACLE may not be functioning properly
body: <p>I have install the Oracle Client 10.2.0 in my windows 8.1 machine. After installation this oracle client is able to connect with the database when we login in as a Administrator into the machine/pc. If we are login with the normal user into machine/pc then we are not able to connect with the database. In this scenario the oracle client application is getting close after enter username, password and database name and press button to connect into oracle client/Sqlplus to connect. </p>
  
  <p>We are getting the below error after type sqlplus from the command prompt from normal user login.</p>
