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

Please clarify the following doubts
1) Can we install oracle client 32 bit on windows 2012 64 bit ?
2) Can we install Both (oracle client 32 bit and Oracle client 64 bit) on windows 2012 64 bit ?

Yes for both questions.
When you like to install both 32 bit and 64 bit on one machine, follow this instruction: BadImageFormatException. This will occur when running in 64 bit mode with the 32 bit Oracle client components installed
Otherwise you have to shuffle around with PATH and other environment values, resp. registry entries.
Yes. Depending on the client applications you sometimes need both. You can install each in it's own Oracle home.

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 ).
I have installed 64 bit oracle (11.2g) on my windows server 2012 R2 64 bit. All works fine with sqlplus.
Now my software is still 32 bit and when I try and connect, it get an error "Provider cannot be found. It may not be properly installed.".
Is this because I am trying to connect 32 bit software with 64 bit oracle? Or something else might be wrong?
Install an oracle 11G 32 bit client in another Oracle home.
I've installed Visual FoxPro driver from this link on my 64 Bit Windows 7 Home Premium OS and tried to register vfpoledb.dll using REGSVR32. I could able to register this dll but when run my application which accesses VFP database is throwing the following error:
System.InvalidOperationException: The 'VFPOLEDB.1' provider is not registered on the local machine.
The same application is working fine in 32 bit Windows 7 Home Premium OS without any issues. I have googled for 64 bit VFP driver and found out that there are no VFP drivers for 64 bit OS from this link. Kindly help me to resolve this issue.
I have found out that there is no 64 bit VFP Driver for 64 bit OS. All we have to do is to change the build option in project properties and set the Platform Target to X86 instead of Any CPU. Build the application for X86. Please refer to this for more details.
It's a bit late, but may help somebody else:) You can use Advantage OLE DB Provider for Windows 64-bit, which works like VFPOLEDB. Example in python:
conn = win32com.client.Dispatch('ADODB.Connection')
dsn = 'Provider=Advantage OLE DB Provider;Data Source=%s; ServerType=ADS_LOCAL_SERVER; TableType=ADS_VFP;' % folder
conn.Open(dsn)
cmd.CommandText = 'ALTER TABLE test ALTER COLUMN area NOT NULL'
cmd.Execute()
A blog post by Eric Selje, of Salty Dog Solutions, describes how to run the 32-bit drivers on 64-bit Windows. (You must set them up in the 32-bit ODBC Administrator.)
Visual FoxPro, a 32-bit application, runs just fine on 64-bit machines.
Visual FoxPro cannot use 64-bit ODBC drivers however.
You can use 32-bit ODBC drivers on 64-bit Windows, but you must set them up in the 32-bit ODBC Administrator. This is not the one that’s
going to come up if you go through Control Panel. To invoke it, run
C:\Windows\SysWow64\odbcad32.exe and add your DSNs there.
Do not just Start, Run, ODBCAd32.exe, as it will not bring up the right one.
The 32-bit drivers for SQL Server come with Windows 7 x64, so you don’t have to download them.
I'm trying to access an Oracle Database from a program I'm writing on Windows 7 64bit. Whenever it initializes the client, i get a BadImageFormatException complaining that I'm trying to use a 32bit client in a 64bit environment. I've tried to compile the program in any way (Any CPU, 32, 64 bit), but it did not solve the problem. Any help?
I would guess that the error message is correct. You have a 32 bit Oracle DLL that you use from a 64 process. The Oracle DLL probably does some interop's with native code, that may require it to be processor specific.
There are several ways to solve this.
Option 1: Get the 64 bit Oracle DLLs.
Option 2: Make sure that your process is 32 bit.
.NET exe files marked for AnyCPU will start a 64 bit process on a 64 bit operating system. But if you mark your EXE file for x86 then it should work. For Web applications you have to set a 32 bit flag somewhere in IIS.
You need to configure your Project to target the .NET 4 Framework, by going to Project-Designer -> Target Framework.
Then you need to delete the old Oracle dll, and use the new 64-Bit-Version of the Oracle dll that is included in the .NET 4 Framework.
