ERROR: Attempt to load Oracle client libraries threw BadImageFormatException.
This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.
I am running an application in Visual Studio 12 and first I installed Oracle 11g 64 bit on Windows 7 64bit after than it was showing the same error Attempt to load.
Then I installed SQL developer 32 bit mode using jdk 32 bit then my report mailers that is also developed in the same application started working but my application that I used to run on local host is not accepting my credentials and displaying the same error when checking data connection in server explorer.
I tried installing both the 32 bit and 64 bit and changing configuration manager mode to everything(cpu , 64 bit , 32 bit ).

Below is the Oracle Documentation for this error:
*This error causes confusion when an Oracle client has been installed. On 32-bit Windows it is enough to install the Oracle client to resolve the error. However on 64-bit Windows you must first check if the process that throws the error is 32-bit or 64-bit, then install the 32-bit or 64-bit client accordingly. I.E. If you are using a 32-bit application like Excel or Access and you have installed the 64-bit client then you will get this error.
This error will also be thrown if you are using a 64-bit application and have the 32-bit client installed.
Another scenario that can throw this error is if you are using Business Intelligence Development Studio (BIDS) with SQL Server and SQL Server Integration Services (SSIS). Some parts of these products are 32-bit and some are 64-bit, and for all these to work together you will need to install BOTH the 32-bit AND the 64-bit Oracle clients.
To check if a process is 32-bit or 64-bit, open Task Manager via either Ctrl-Alt-Del or right-clicking on the task bar, then locate the process name in the Processes tab. If there is a *32 after the process name then the process is 32-bit and will need the 32-bit Oracle client. If *32 does not appear then the process is 64-bit and will need the 64-bit Oracle client. (NB: This is only valid for 64-bit Windows. On 32-bit Windows all processes are 32-bit and 32 will not be displayed in Task Manager.)
I have an SSIS package that I've developed in Visual Studio 2015.
The package is connected to an Oracle DB and a local SQL Server DB as input and output respectively.
I had some issues connecting the package to the Oracle client in the past due to 32 vs 64 bit compatibility issues (machine is 64 bit, Visual Studio is 32 bit).
I fixed that by installing both 32 and 64 bit oracle libraries on my machine and changing the Project property 'Run64BitRuntime' to False.
However, I've now exported the project as a .ispac file to SSMS to try schedule it. However, I'm getting the error I had with Visual Studio a while back, "Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit oracle client components installed".
Visual Studio and SSMS are both 32 bit applications, so why is this issue popping up again? My project should be set to use 32 bit libraries by the looks of it and runs fine in VS.
Does SSMS have it's own toggle for which driver to use?
Ok I managed to solve the problem somehow. You can change the package execution settings in SSMS under advanced settings.
You can also choose what settings you want to run in a scheduled job so this allows me to run all the packages at 32-bit runtime.
Picture here showing which option
I have been trying to connect to an Oracle Database using SSIS(Visual Studio) using ODBC as the connection manager.
My OS is Windows 7 (64 bit), Visual Studio 2010 (32-bit) and Oracle 11G is 64 bit.
While connecting to Oracle 11G using Visual Studio via ODBC I am greeted with the following error:
'The specified DSN has an architecture mismatch between driver and application'
This is understandable as Visual Studio is 32 bit and the server I am trying connect to is 64 bit.
Possible solutions?
Install both the 32 and 64 bit providers for oracle. This will allow you to configure the connection (in 32 bit) and run the package in 64 bit.
Also, check out attunity: https://www.microsoft.com/en-us/download/details.aspx?id=44582
This is a free oracle source and destination component from Microsoft. You'll find that it uses native oracle interfaces and runs much faster than ODBC.

I am using Windows 10 64 bit and Oracle client 32 bit (It's my company requirement). But when I open some existed program, it display a dialog with error:
Attempt to load oracle client libraries threw badimageformatexception.
This problem will occur when running in 64 bit mode with the 32 bit
Oracle client components installed
I had fixed by add Enviroment variables but it's not working. I am searching around Google, but the solution almost about fix on Visual Studio when developing application.
These program is existed, not run from Visual Studio.
How should I do to make application which using Oracle client 32 bit on OS 64 bit?
A 32 bit application requires also a 32 bit Oracle Client. A 64 bit application (resp. "AnyCPU" on windows 64 bit) requires a 64 bit Oracle Client.
Unless you use the ODP.NET Managed Driver (see here) there is not way to get rid of it. One solution is to install both, 32 bit and 64 bit Oracle Client, follow this instruction: BadImageFormatException. This will occur when running in 64 bit mode with the 32 bit Oracle client components installed
Oracle installed on the server is 10.2.0.3 Enterprise Edition 64bit (10g).
ODAC is showing version as 10.2.0.2.20 is on a Windows 2008 x64 machine.
Error I run into when I run my app in my test environment in above machine is
The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception.
I tried using .Net Oracle namespace and I get this using a version from
C:\Windows\Microsoft.NET\Framework64\v2.0.50727
Error:
Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.
Anyone run into such an issue?
Also what is the right Oracle Client/ODAC to use on Windows 2008 x64 machine? Anyonen have a link?
You seem to have installed the 32 bits Oracle client, or you must have a 32 dll masking your 64bits client. You need to install the 64bits client so that 64 bits dll can be accessed by your app. Look for an oci*.dll in your path.
Also look into the registry under hklm\software\oracle to see how many 'homes' you have.
Finally if you have toad on that client look at the home selector in the connection dialog box. It will show incomplete or inoperative homes in red.
