Already gone through those discussions.
I also have the same problem as you. I did what you have done but still get the same error message. Has anyone heard from Landesk Support on this?
I have worked through this problem and attached instructions for deploying .EXE or .MSI packages to machines for LaunchPad. It works for me I hope it works for you. It may not be the best way but it worked to get the program to run/install from Launchpad with no errors.
