Can't install conponants notes 8.5

When i used 8.02 I installed the SideNote componants in my sidebar.

To get the install function under File → Application → Install I added “com.ibm.notes.branding/enable.update.ui=true” in

\framework\rcp\plugin_customization.ini.

BUT BUT After uprgading to 8.5 I can’t find the “install” and “com.ibm.notes.branding/enable.update.ui=true” is in the plugin_customization.ini file ???

Please advice
