XCopy allows complete installation and configuration customization. ODAC XCopy packages include:
This is for their latest Oracle Data Access Components, 64-bit ODAC 11.2 Release 4 (11.2.0.3.0) for Windows x64. I want to use the developer tools (ODT) but they aren't available in 64 bit (probably because VS2010 is still 32-bit). From the site:

Important: The 32-bit Oracle Developer Tools for Visual Studio download is required for Entity Framework design-time features. The above download fully supports Entity Framework deployment, but does not contain design-time tools.
If it matters, this is for a WCF service running on a virtual Windows Server 2008 R2 machine. What I have done semi-successfully is force everybody to 32-bit operation, but that seems a little silly if 64 bit is supported as they claim it is.
Last year I was working on a Data Warehouse project where we were going to use SSIS (SQL Server Integration Services) to read data from an Oracle Database. The problem was that the SSIS development environment uses 32-bit OLE DB drivers, but the SSIS runtime uses 64-bit drivers (this could be changed to 32-bit, but it was not a good solution). So we needed to have Oracle OLE DB 32-bit and 64-bit drivers side-by-side. This was trickier than expected. Here is how we solved it!
The ODAC OUI gives you a graphical user interface for installation, but it only provides you with 64-bit version of the drivers. If you need 32-bit drivers, you will have to use the command-line ODAC XCopy.
The trick is to use Windows symbolic links. The Windows system folder will be in different locations depending on 64-bit or 32-bit mode. Using symbolic links, you can therefore create a path that points differently for 64-bit applications and 32-bit applications.
I am trying to connect to a Oracle DB using Power Bi desktop 64 bit. I have downloaded ODAC122011_x64 from the oracle site and configured the tnsname.ora with my server details. The file is on my C Drive C:\app\myname\product\12.2.0\client_1\Network\Admin\Sample
To connect to an Oracle database or Oracle Autonomous Database with Power BI Desktop, install Oracle Client for Microsoft Tools (OCMT) on the computer running Power BI Desktop. The OCMT software you use depends on which version of Power BI Desktop you've installed: 32-bit or 64-bit. It also depends on your version of Oracle server.
As alluded to in the question you linked to, some SQL Server tools/applications are 32-bit only. The main SQL Server application (sqlservr.exe) is 64-bit (32-bit may still be available as well, not certain about that for the latest versions); however, some of the supporting tools, perhaps most notable SQL Server Management Studio (ssms.exe), are only available as 32-bit applications.
A 32-bit application (include drivers like ODBC, OLEDB, etc.) can use only the 32-bit Oracle Client, resp. 64-bit applications require the 64-bit Oracle Client. Some applications are not available for 64 bit or not very common, e.g. MS Office which may utilize ODBC.
PROBLEM
An application I use very frequently uses the Oracle 32-bit ODBC drivers to read and write to oracle databases, however, I need the 64-bit Oracle ODBC Drivers to allow Excel to query the same/other oracle tables.
Hello, This is literally giving me headache for the past 10 days. Unable to resolve the issue. Basically I'm trying to create a data connection from an excel file to an oracle database. I have full access to the database but the problem is; whenever I try to create a data connection, these errors throw up.
Is there a legitimate best practice way to do this? Specifically I'm wondering about whether each client needs to be in its own BASE directory (say C:\oracle and C:\oracle32) or if they should be within the same base direct but have their own client folders.
I had the same issue. Oracle 12.2.0.1 both 32 and 64 bit clients installed on the same Windows 10 machine with Office 365 (64 bit). My 32-bit apps stopped working. All I had to do was edit the System Environment variables and DELETE the entry for ORACLE_HOME, then reboot. Didn't need to create any symlinks.
The Oracle Database 12c Release 1 (12.1) on Windows installation package (32-bit client, 64-bit server, and 64-bit client) includes a XCopy installable version of ODP.NET, Managed Driver. Each of these installation packages contains both the ODP.NET, Managed Driver assemblies for 32-bit and 64-bit .NET Framework.
There are two versions of Oracle.ManagedDataAccessDTC.dll, one for 32-bit .NET Framework and one for 64-bit .NET Framework, installed with ODP.NET, Managed Driver. While both versions of Oracle.ManagedDataAccessDTC.dll are fully managed, they must be platform-specific, because the MS DTC application programming interfaces are unmanaged code. Thus, ODP.NET, Managed Driver enlistment and commit functions call either the 32-bit or 64-bit MS DTC, depending on the platform.
Oracle Data Provider for .NET (ODP.NET): A database connectivity layer for use with .NET applications, like Meridium APM. You can use these instructions to install both the required 32-bit and 64-bit versions.
Read the 32-bit Post Installation information, and complete any necessary steps, as indicated in the command prompt window. For example, you may need to change the NLS_LANG to a value that is compatible with the Database Server. If you are asked to restart the machine, do not do so until after the 64-bit version is installed.
To connect to an Oracle database with Power BI Desktop, the correct Oracle client software must be installed on the computer running Power BI Desktop. The Oracle client software you use depends on which version of Power BI Desktop you've installed: 32-bit or 64-bit. It also depends on your version of Oracle server.
Automation Studio runs in 32 bit mode and the same is expected.
Community edition supports both 32 bit and 64 bit oracle client. Refer this pdf for ODAC installation and install both 32 bit and 64 bit in case only 64 bit is not working
This issue is due to conflict of 32bit and 64 bit files.
I have installed oracle 19c 64 bit database on windows 8.1 (64 bit).
The UI path is 32 bit installed on 64 bit windows. I went through forums and it was suggested that I should install oracle 32 bit instant client. When I tried to do that it was giving some error due to oracle_home directory over-ridding.
Though I downloaded oracle client 64 bit version and also 32 bit version but I have not installed.
With Oracle database 19c 64 bit installed on my machine, ODP.NET came by default (containing relevant dlls for both 32 bit and 64 bit). Hence it worked. I was able to fetch data from database.
To help guide customers on how to install, configure, and test both the 32-bit and 64-bit Oracle Data Provider for .Net (ODP), Oracle Provider for OLE DB (OLEDB), and Oracle ODBC Driver (ODBC) Oracle Software on 64-bit Windows.
When using the Oracle software on 64-bit Windows, some will need to install both 32-bit and 64-bit Oracle software. First a few facts/Tips about 32-bit and 64-bit Oracle software installed on 64-bit Windows.
Run the Net Configuration Assistant located under Start -> All Programs -> Oracle -> Oracle_Home_Name -> Configuration and Migration Tools -> Net Configuration Assistant for both the 64-bit Oracle software and 32-bit Oracle software. Since both will need to have the sqlnet connection configured. The configuration for this is exactly the same for both 32-bit and 64-bit. Here are the instructions:
A major problem is that depending on your software mix, it might be necessary to install the 32-bit and the 64-bit versions of the client, which is a challenge on its own, if you have to make both versions available on one machine.
The highlighted driver is the Oracle 64-bit ODBC driver that I did install on my system before. You can download it as part of the 64-bit ODAC. The 32-bit version is, of course, part of the 32-bit ODAC download.
Again, there are some same small changes that have to be made to the script if you want to use the ODBC driver. By using the 32-bit driver, these changes include: We have to replace each occurrence of the string Oracle.ManagedDataAccess.Client.Oracle withSystem.Data.Odbc.Odbc and use a different connection string, as shown here:
Checking Oracle client software: There are three methods for checking the Oracle client software. Windows has a different lib directory for 32-bit software and 64-bit software. The fastest way to see if an Oracle Client is 64bit or 32bit, too look for "lib32" and "lib" folders under ORACLE_HOME.
RESOLUTION 2:
If logged into SQL Plus, the banner will tell you 64-bit if the 64-bit version is installed. If it does not specify 64-bit then it is 32-bit (even though it does not explicitly say so).
Bring up a command-line prompt.
cd into the Oracle client directory. In the oracle client directory, there should be a bin folder. In the bin folder, there should be an executable called tnsping.exe 006ab0faaa
