I have the same issue. I would like to install some plug-ins that I now miss. I have the “Advanced Menus” option check-marked but still no “Install” option under “File → Application”.
I tried the old method of adding “com.ibm.notes.branding/enable.update.ui=true” to the plugin_customization.ini file which only lead to the following error during Notes start-up: “‘EUM UI Job’ has encountered a problem.”
I am now able to add plug-ins again in Notes 8.5 GA. You need to modify the <install_dir>\framework\rcp\plugin_customization.ini file by adding the line “com.ibm.notes.branding/enable.update.ui=true” as per the instructions found here:
Subject: There is a way to roll-out plug-ins neatly
Step 1: Place your plug-in in an accessible update site (maybe using the Domino Update Site template).
Step 2: Create a Domino widget catalog and add to it a widget that installs your plug-in.
Step 3: Specify this widget catalog and whichever widget categories you want to auto-provision as part of a Desktop Policy Settings document.
That will automatically provision the widget to all users covered by the policy. You can read more details in Technote 1305829: “How to use a Notes widget to deploy a new plug-in to an existing Notes installation” at http://www-01.ibm.com/support/docview.wss?uid=swg21305829
By the way, if you just want to give people the ability to install plug-ins for themselves, you can also enable this through the Desktop Policy Settings.
Policy setting for provisioning is Enabled and parameter com.ibm.notes.branding/enable.update.ui=true is set in <install_dir>\framework\rcp\plugin_customization.ini file.
Also, client was restarted several times after policy change. What am I doing wrong?
