I have been tasked with writing an installer with a silverlight out of browser application. I need to. get the version off a local EXE check a web service to see that it is the most recent version download a zip if not unpack the zip overwrite the old EXE start the EXE This installer app is written in .NET WinForms now but the .NET framework is an obstacle for people to download. The recommended solution is to use a SLOOB however i am not sure how to assign full trust. If i assign full trust can I start a process. Thanks
