Installing Issues

Hello Experts,

I am having a problem with Oracle Client install.

Situation I have oracle 64 bit db installed in my system and works fine. Now one of the oracle application requirement is to install 32 bit in my 64bit windows standalone system.

Now i have installed 32 bit oracle client in drive C where as my oracle db is in drive E. But when i am trying to connect to db from my client then i cant. It gives me ora-12557 error(tns adapter problem).

I have configured tns in my client but still not sucess.

My environment system vairable path is E:\app\Prakhar\product\11.2.0\dbhome_1\bin;C:\app\Prakhar\product\11.2.0\dbhome_2\bin;
