    Hello
    I'm trying to install 32-bit Oracle Client to the 64-bit Oracle Database on Windows 2008 server R2x64. I need it to run my 32 bit application.

    What have I done:

    1. Installed 64-bit Oracle Database (10.2.0.4). My oracle home is: "C:\oracle\orcl" and my service name in tnsnames is: "orcl"
    2. Installed 32-bit Oracle Production Client (10.2.0.3) to the: "C:\oracle\orcl1"
    and copy tnsnames from C:\oracle\orcl\network\admin to C:\oracle\orcl1\network\admin
    3. In cmd prompt I used: set oracle_home=c:\oracle\orcl1"
    4. In Environment Variables Path I put: "c:\oracle\orcl1\bin"

    .......but it still doesn't work. I have no idea where I did mistake and what to do.
    When I'm trying to run my apllication I have an error: Cannot load an IDAPI service library. SQLORA32.dll

    Thx for advice

    Add c:\oracle\orcl1\lib to your path BEFORE the entry for the 10.2.0.4 Oracle home and try again.

    Thank's for replay.
    I've installed the newer version of oracle client 11g and everything works fine.
