Does sllauncher mark a number of suggestions inside Windows Event Log in case of problems? I run my application inside Windows 7 through "sllauncher /emulate" and I contain one case while the silverlight doesn't launch in any way. No indications, no exceptions, no log not anything. I erased the Windows 7 User Profile and formed it all over again and the identical Silverlight worked as anticipated. Should I need to make use of sysinternal "Process Monitor" to discover the sllauncher issues otherwise will the sllauncher writes inside EventLog?
