Oracle.Dataaccess.dll deploy windows application

Question

I have a windows application that I developed in VS 2005 on XP. It access the DB via the oracle data provider. I just switched to vista and was adding some new items ot the application and then tried to redeploy it. I had to add a new installer to the project and whne i try to run the applciation on the client machine after it installs i get an unhandled exception. After remote debugging i get the following error. {"The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception."}. I notice that the client on a previous install of the application uses 10.2.0.100 and the new client uses 2.102.2.20. Is this my problem?
