Steps to reproduce:
1) Setup Windows Server 2012 and IE 10 environment, the machine should also have an existing project with at least one web test (very simple)
2) Use ArtOfTest runner to run the web test (eg. ArtOfTest.Runner.exe test="C:\Users\Telerik User\Documents\Test Studio Projects\TestProject1\Webtest.tstest")

Expected result
ArtOfTest runner executes the test

Actual result
IE10 browser is launched however it remains blank and the test does not continue, example execution log below:
