Unrecognized attribute 'type'

Hi,

Just tried to install FileVista & the error message below I got when I tried to run configuration. I am running Win2003 Server - R3, AspNet 2 / 3.5

Thanks for any suggestions.

Error Message:
Unrecognized attribute 'type'

Line 3:      <configSections>
Line 4:      <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

Source File: C:\Inetpub\mil-tach\web.config Line: 4 

Please make sure that ASP.NET 2.0 is the active version for the installed FileVista folder. This can be checked on the ASP.NET tab of FileVista folder's properties dialog box in Internet Information Services Manager.
