IBM Lotus Notes 9 upgrade not installing 'Client Single Logon Feature' with silent install
I have created a package to install Notes 9 with the specific notes features that i require. The package installs fine when installing on a clean machine (Server 2003 x64) but when i try to install the package on a machine with a previous version of Notes already installed (Notes 7) it does not install the Client Single Logon Feature. Part of the upgrade is to uninstall the previous version so i'm not sure why it is stopping this from happening. Here are some of the entries from the log files....
Log file from server with no previous notes version installed

I have tried to add the following property to the package but it still made no difference....
Does anyone have any suggestions apart from uninstalling the previous version before performing the install.
