Treige has suggested a cool way to install Maya Bonus Tools for Maya 2011 Subscription Advantage Pack.
By the way, if we have installed bonus tools manually, adding paths to the env variables MAYA_PLUG_IN_PATH and MAYA_SCRIPT_PATH, we could notice that the help item doesn't work. In this case we have to open
and replace the line:
-c "bonusToolsHelp \"docs/bonusTools.html\""
-c "bonusToolsHelp \"/docs/bonusTools.html\""
This is the sign that a manual install doesn't work fine.
