Hi! I'm trying to install the HP Bluetooth Software for laptops (both HP-package SP28358A and SP28427A) on various HP laptops with the same fatal result: This installation requires administrative privileges. The drivers are added during install without any issues, it's when I try to add the "application" part of the package that it fails. I can get it to work if I set the unattended install to auto-logon after it's finished and then I install the SW manually. (Which is ofcourse not what I want....) However, if I use the RunOnceEx-method it fails, running it from cmdlines.txt fails and using the [GUIRunOnce] section also fails. I've tried both with a "setup.exe /S /SMS" approach and to install the MSI file directly with "msiexec /i BTW.msi /qn". Same negative result. Both methods work if I run them manually after the install. Common for the automated methods (RunOnceEx, cmdlines.txt and GUIRunOnce) seems to be that the explorer isn't started/running, could this be the problem? Any ideas? /Anders
