Dear Experts,

I have a 32 bits ASP.NET application that works with Oracle Data Client.

I'm in process to migrate this app (currently runs on a IIS6) to a new IIS7.

On the new server I have (I need to have) both 32 and 64 bits Oracle clients.

The problem is that when I try to load the app, a BadFormatException is raised from IIS7. The error is saying that I'm trying to load the 64 bits Oracle client, when I want to load 32 version.

How can config my app or "I don't know what" to use specifically the 32 bits client?

Thanks in advance.

This sounds to be a problem with the oracle connector (possibly installed in x64 mode)
See the link below for a means to run 32 bit and 64 bit oracle side by side:

I am assuming based on your post there are no issues with running 32 bit apps on your IIS server and you have already enabled 32bit apps for .net.

Very interesting solution proposal ... I'll try it and come back here with the results.

You are right, I have enabled 32 bits flag on application pool.
