Exception thrown attempting to launch Internet Explorer

[John]

Hello

I am getting this error when I try to run a recorded web test against internet explorer:

System.ApplicationException: Exception thrown attempting to launch Internet Explorer. Please make sure Internet Explorer is properly installed and you are able to launch it.

The internet explorer window opens up, but nothing else happens, the pages starys on About:Blank

There are numerous posts on this forum which tell you to disable browser plugins and a few others. is there any definitive place where all the causes are stored in a kb article?

Cheers
Alex

Hi John,
    here's it is:

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.

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):

Please make sure Internet Explorer is properly installed and you are able to launch it. ---> System.InvalidOperationException: No process is associated with this object.
