So this ticket looks similar to the other ticket you posted. Please
respond back in Ticket #319288 and I am closing this thread to better track this issue in Ticket #319288. The following is just a copy of my reply in the other tickets:
Thanks for the post and I'm sorry you ran into this problem. Typically, this happens when you uninstall WebUI Dev edition and try to open the WebUI tests in Visual Studio.
From your download and purchase history, do you just have WebUI QA edition installed on the machine? The QA edition shortcut should be in the Telerik Start Menu -> Telerik folder.
If there is no QA edition installed, please also check Add/Remove programs for Telerik WebUI Test Studio 2010.1. If there is that entry in Add/Remove Programs, please try logging into the user account you first installed WebUI and see if you can open up the WebUI tests with that user account.
If you cannot open the WebUI tests in any user account and QA edition is not installed, please uninstall any Telerik WebUI Test Studio 2010.1 entry in Add/Remove Programs, then reinstall the latest Dev Edition here
and activate with your WebUI Activation key.
All the best,
the Telerik team
