    We have done this with several servers and have found the order that Oracle is installed is important. Below are some of our notes from the steps we use.

    Install Oracle 11 32 bit

    Install in C:\oracle, home = client_32

    Install Oracle 11 64 bit

    Install in C:\oracle, home = client_64

    Make sure Path env var contains folder path to client_32 and client_64, client_32 should be listed first

    TNS_ADMIN env var should have folder path to client_32

    Run regedit to change settings

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI and

    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSDTC\MTxOCI

    below are correct settings:

    OracleOciLib = oci.dll

    OracleSqlLib = orasql11.dll (old: SQLLib80.dll)

    OracleXaLib = oraclient11.dll (old: xa80.dll)
