Oracle Database Discussions

Hi,
I need to install oracle client 32-bit version and then 64-bit version for oracle Hyperion based on the install guide.

I am able to install each version by itself fine and able to connect to the database but not when together.
1. Installed 32-bit
2. Then tried to install 64-bit version. During the last step of the configuration got: [INS-20802] Oracle Net Configuration Assistant failed.
3. In the Start, All Programs, I only see the first, but all the values have been modified to the point to the second.
4. I can run sqlplus from the bin folder of the first and connect to the DB, but not the second.

Here from the log:

I did set ORACLE_HOME and when I check the environment in new command window don't see any.
In the PATH I do see both: C:\oracle\product\11.2.0\client_2\bin;C:\oracle\product\11.2.0\client_1\bin;

Hope this is possible?
Thanks
