AJAX TOOLKIT NOT WORKING ON PRODUCTION MACHINE

Hi to all,

I have a small webform application (framework 4.5) with AJAX ToolKit components (modalpopup and updatepanel). All works fine in VS2013 but when i publish (file system) to my Windows server 2008 R2 (IIS7.5) these components doesn't work. No errors are displayed, when i click on button that call modalpopuo nothing happen.

Solutions found in google and on this site doesn't work for me.

I use toolkitscript manager and dlls are in bin folder

i have tried to add <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> as reported in this link http://forums.asp.net/t/1768317.aspx but no result.

My version of AjaxToolkit is 4.5.7.1005 (i tried to update ajaxtoolkit form nuget but on productin machine i get system.web error. on vs2013 it works)

Ideas?

Thanks
