Error HTTP 500.19 after installing HPTrim Webclient

I installed Hp Trim Webclient (v7.3 for trial) in my Windows 8.1 Pro machine with HP Trim 7.30.

At the very first time I got the error "Error when connecting to dataset TRIM '45' in workgroup server 'xxxxx'. I follow the instructions to create a new app pool in IIS (I call it Web Trim) and put the trim web client in this pool with user "TRIMServices". After that this error disappears, but a new one emerged. The page displays the following info:


Error HTTP 500.19 - Internal Server Error


The requested page cannot be accessed because the related configuration data for the page is invalid.

Error detailed information:


  • Module:   IIS Web Core
  • Notification:   BeginRequest
  • Controller:   Not determined yet
  • Error code:   0x800700b7
  • Configuration error:   The defined section 'system.web.extensions/scripting/scriptResourceHandler' is duplicated
  • Configuration file:   \\?\C:\Program Files\Hewlett-Packard\HP TRIM\Web Client\web.config
  • URL address requested:   http://localhost:80/HPTRIMWebClient/default.aspx
  • Physical access path:   C:\Program Files\Hewlett-Packard\HP TRIM\Web Client\default.aspx
  • Start session method:   Not determined yet
  • Start session User:   Not determined yet


Configuration origin:

   13:         <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/>

   14:         <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35">



Attached please find the web.config file.


I didn't find the duplicated section mentioned in the Configuration error, only the original.


Could someone help me to solve this problem?


Thanks in advance for your attention.
