Could not load file or assembly

I have an ASP.NET website that uses the Oracle.DataAccess.dll. I have version 10.2.0.100 and 1.111.6.0 in the GAC of my local machine, but only 10.2.0.100 on the dev server. When I deploy the website to the server and run the website, I get this error before the website even loads:

"Could not load file or assembly 'Oracle.DataAccess, Version=1.111.6.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"

I guess I need to build my app against the 10.2.0.100 version but I don't see how to do that. If I remove the 1.111.6.0 version from the GAC on my LOCAL machine and try to rebuild, I get the error above.

How do I resolve this issue? How do I build against a certain dll even if there are more than one version of that dll in the GAC?

If your server is a 64bit machine, enable execution of 32 bit applications in IIS.

Application pools >> Advanced Settings >> Enable 32bit Applications.
