在Win 10 64位上使用Oracle Client 32位

Question

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?

Answer 1

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
