ORA-12154 by using 32-bit application on 64-bit windows 7

[AndyOracle2]

Hello,

at the moment we migrate to windows 7. Some of them are 64-bit installations.

Here is the problem, that our applications, who are using doa do not work.
We installed the oracle 10.2.0 32-bit client on windows 7 with 64-bit.

SQL*PLUS and SQL-Developer is working fine.

We can resolve the SID by tns-ping without any problems and we can select data from the tables.

But if we try to start our 32-bit application, the error ORA-12154 occurs.

Have you got any idea what we can check or something else to solve this problem?

Thank you very much!

Perhaps you have installed your application under the C:\Program Files(x86) directory? Due to an Oracle Client bug you will get this ORA-12154 error when connecting from a directory with parentheses. You will need to upgrade to an 11g client, or reinstall the application in a directory without parentheses.
