Unable to Install Silverlight 2.0 SDK?

Hi,


I am unable to install Silverlight 2.0 SDK on Windows Vista Home Premium.


I was getting the following error: "Error 1500 Another Installation is in progress you must complete that installation before continuing this one"


I restarted system and tried to install but again i was getting the same error


Thanks&Regards,
