Force my app to use my dll and no the one in the GAC

Hi all,

I have an application and I am using a specific version of a dll. (In my case Oracle.DataAccess.dll v9.2) when I install my app in my machine all works well, but when I deploy the application in another machine the application works different (the machine where I install have Oracle.DataAccess.dll 10.x) my setup project copy de Oracle.DataAccess.dll V9.2 to the Program files folder. But when the application run use the dll installed in the GAC.

My Question is; is there a way I can force my app to use the dll in the Program Files and no the one in the GAC?

Some info about my APP.

Windows Form
Framework 1.1
Visual Studio 2003

Thanks
Alberto.
