[Cherry]

Hello,

silverlight4 SDK installed.

Hi Cherry,
     this issue is not related to the version of Silverlight you're using.

Try adding a WaitForExists step on a Silverlight element before the LeftClick step (screenshot 1).
This will assure that the Silverlight application is properly loaded. You can increase the timeout on this step (10 seconds by default).

Also try increasing the Silverlight connection timeout (screenshot 2).

Do you still get the same issue?
