I am getting error as attached, while trying to connect to my database oracle 11.1.0.7 using ER Studio. How ever I can connect using SQL Developer and sql prompt ( I mean tnsnames.ora settings are correct).

Could you let me know how to resolve it?

Note: 1. Other guys are able to connect (using Windows XP).
           2. Please find the error details in attached docs.

do you have two oracle clients installed on your system, if not check the directory C:\WINNT\system32 should have one oci.dll file if it is more than one please rename the others.

also check the that your oracle bin path is exists in your system variables.

also check this doc for more info.

Make sure your Oracle client matches the bit version of ER Studio.  If ER Studio is 32bit, use a 32bit Oracle client.
