Hello .... I have an application server with Windows Server 2008, IIS 7 and Oracle Data Provider 11G. The website was set up. NET 2008 has made reference to the oracle, and to run from the application working properly executes the SQL without problem, but to make the creation of a website The IIS 7, and test its functionality, displays the following error

 Could not load file or assembly 'Oracle.Web, Version = 2.111.6.20' or one of its dependencies. The system can not find the file specified.

The problem may be a compatibility between the version of Oracle 11G and IIS 7.0, I do not know if there is an additional component to the IIS 7.0 can recognize the version of Oracle as a provider of data? Please I am attentive to their solutions .... Thank you
