Please try using the .NET Framework 4.0 specific builds of Eagle and Garuda for the latest release (Beta 50).  The downloaded file will be marked with “NetFx40_”, e.g.: https://download.eagle.to/releases/1.0.8192.54321/EagleBinaryNetFx40_1.0.8192.54321.exe

EDIT #1: Also, is there a “UIAutomationClient.dll” file somewhere on the system in question?
