Upgrade Compile Error

[Ambu]

VS2010
.Net 4

Trying to change the Telerik version from 2010 to 2011.2.915.40.

I am getting the following error when trying to compile:

Error 11 Could not load file or assembly 'file:///C:\Program Files\\Application Libraries\Bin6.5\Telerik 2011\Telerik.Web.UI.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) C:\abc\Branch\SGEN abc

Tried adding the following web.config key, but no change in build error:

 

 

<system.webServer>
  <handlers>
   <add name="Telerik.Web.UI.WebResource"  path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2011.2.915.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" />
  </handlers>
 </system.webServer>

Any help will be appreciated.

Hello,

The Telerik.Web.UI.dll needs to be unblocked by right clicking and selecting the unblock checkbox. The problem is also discussed in the following article:
Visual Studio Project Sample Loading Error: Assembly could not be loaded and will be ignored. Could not load file or assembly or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515).

Kind regards,
Rumen

Perfect!  This fixed my problem!

Fixed my problem too. I had compressed it with Winrar and forgot to unblock it before unpacking.
