There are a couple of points to this problem:
* The installation for Mashup Sites for SharePoint (MS4SP), did work. But the telerik feature is just not activated in SharePoint. What you need to do is follow the configuration instructions in http://www.jackbe.com/prestodocs/v3.0/mashupsites4sharepoint/InstallationConfiguration2007.pdf to activate the Web Parts features. This will activate telerik.
* Presto 3.1 is not guaranteed to be compatible with SharePoint 2007. You can install Presto 3.0, which is compatible with SharePoint 2007. Compatibility for Presto 3.1 and SharePoint 2007 will be available in a future release that is coming out soon.
Having said that, I owe all our users an apology for an error in the release notes for 3.1. The Systems Requirements section erroneously implied that Presto 3.1 and SharePoint 2007 were compatible. This has been fixed in the Presto Library and in release notes, but did not make it into the release notes that were shipped in the 3.1 download.

Which feature activates Telerik? I had already activated (per the instructions in InstallationConfiguration2007.pdf): Presto Web Parts (in Site Collection Features), Mashup Sites for SharePoint Custom Actions and Presto Administration (the last two in Site Features.) The Presto List Action feature is not listed in Site Features.
Hi Sam,
There is another feature at the Web Application level that should automatically be activated when you activate the Presto Web Parts feature . Can you go to Central Administration, click on Application Management, Manage Web Application Features under SharePoint Web Application Management section. Then select the web application that your site is hosted by and verify the Telerik feature has been activated? If it is not activated, please do so and reset IIS. If it is activated and you are still seeing the error can you please attach your web.config file for your web application to this post? Thanks.
I get the following error when I try to add a Presto App Web Part to a SharePoint Web Part Page:
Server Error in '/' Application.

I have a trial version of Presto 3.1 running locally on my host computer, and SharePoint 2007 running in a Windows 2003 Server virtual pc. I installed Presto Mashup Sites for Sharepoint from the downloaded file "MashupSites2007_2010_9_27_10_20_PM.msi." I confirmed the connection when I configured the Mashup Server in SharePoint.
If I add the following line to web.config (inside the httpHandlers element):
<add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" validate="false" />
Then I get a null reference exception.
It looks like the installation of Mashup Sites for SharePoint did not install all the necessary files. What is the solution to this problem?
Thanks.
