IIS 7 issue

ASP.NET

Hi guys,

I am deploying my website created in .net/asp.net 4.0 and deploying it in IIS 7 in my windows 7.

I am using some infragistic controls and the required infragistic libraries are in the bin folder, but when I run the application through internet explorer it says:

Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Could not load file or assembly 'Infragistics2.WebUI.Misc.v6.3, Version=6.3.20063.1059, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb' or one of its dependencies. The system cannot find the file specified.
Source Error:

But when I run it through firefox, the page is opened but with some script code on the page and also controls are not rendered.

Any ideas?

I have also deployed another test application but it's running smoothly, just this site is having problems.

I have not installed infragistics just added the required DLLs.
