Telerik Testing Framework try to simulate mouse click (UserInteraction.Click) using method SendInput to interact with application, but mouse click does not occur.
The main reason is that method SendInput used in x86 architecture maner.
Structure ArtOfTest.WebAii.Win32.Input does not support that in x64 length of field type 8 instead 4.
The problem is discussed in my question on stackoverflow - C#: The unmanaged method SendInput does not work with different representation of the structure .
The main question is whether the Testing Framework supports architecture x64?
If yes, can you fix that problem?
If no, can you throw exception at test initializing? - It is common practice that users immediately understand the problem.
