Kindly let me know if we can rollback to the previous version using LDMS after installing Silverlight. I am able to deploy the latest version of silver light and uninstallation also possible using LANDesk. But I wanted to know how to rollback to the previous version using LANDesk.
You should be able to create a Software Distribution package to uninstall any application. You just need to know the commands and what (if any) files need to be downloaded/run to do the uninstall.
Also, some of the Patch Definitions have uninstall commands in the, so you can send a job to uninstall a patch. I don't know if/how you updated Silverlight, but you might be able to either use, or borrow from a corresponding Vulnerability in Patch Manager.
