Exception thrown attempting to launch Internet Explorer

Hi John,
    here's it is:
http://www.telerik.com/automated-testing-tools/support/documentation/user-guide/troubleshooting_guide/recording-problems/unable-to-launch-recorder.aspx

Let us know if you're still unable to resolve the issue.

Best wishes,

The problem was with the running of the test, not the recording.

Migrating the application to another machine seemed to work, though this would have been a lot trickier if migration was not an option.

Either way, it seems like its working ok now.

Cheers

Hello John,
  I understand your concern. We can still troubleshoot the original issue if you like to. I'm sure we'll be able to get to the bottom of the issue.

I am having a similar problem. When I run/debug my test, a browser window opens, but remains blank (rather than running my test) and I get the following error (in IE10):
