Thanks Richard . . . the error you posted did include the stack trace. Here's the actual error:

Object reference not set to an instance of an object.at DotNetNuke.Services.Installer.XmlMerge.UpdateNode(XmlNode . . .

The last part of the Telerik install and of the other providers which gave error messages as well is to make modifications to the site's web.config file. Either access to web.config was denied due to insufficient file permissions for the ASP.Net worker process account on the site's root install folder or, more likely, a section of the web.config file is corrupted so that the XmlMerge method could not find the point at which to make the modification. If your web.config file uses a <location> . . .  </location> section wrapped around the <system.web> section, that can also be a cause of this issue.

when using full install package for upgrading, make sure you are not overwriting existing web.config file or database.mdf inside app_data folder. If you did, please restore from a previous backup.

Oops, also, I'm not using the database.mdf file, I'm using a SQL server.
