Is the issue specific toHP support assistant?
Solution: Okay so just simply running the softpaq with a /s at least gets it to install unattended which is enough for my MDT needs. Shame they can't make it a Anyone have any advice on how to add the HP Support Assistant tool to MDT applications list? Unwise to uninstall HP support assistant? And I certainly don't like that HP Support Assistant consumes memory, freezes the computer when running its autoupdating. Call HP support and ask them to tell you where teh zapper is. The zapper is an MIS or EXE that can be excuted and it will remove allof a product usually at all version levels. The unistallstring will not work due to teh temp folder being used for the install.
