I found that you have to install the 32-bit Oracle client (you can download the installer from their website) even if you are running on a 64-bit machine.

In addition, during the discussions people were talking about 32-bit mode etc. This is how you can check / set that for an IIS 7 hosted application. You shouldn't need to change this but I have added here for completeness / future reference.

• Launch IIS 7 and expand the server name node.
• Click on Application Pools node and find the application Pool you are using.
• On the right-hand panel click Advanced Settings...
• In the pop-up box that appears check Enabled 32-Bit Applications setting which is third option from the top.
