Global Support Engineering Operations.
i am using epo 4.6.3 and DLP 9.3.150 for Mac. And After that i choice menu Data Protection/DLP Policy but when i click i can't open it. i dont know problems happen at where.
Before that i was using DLP 9.3 for Windows.
DLPe for Mac recently come out in version 9.3.150.
In it , there is also a new extension.
Did you install the new 9.3.150 extension as well ? or just the client packages?
If you also install the new extension, most probably when you click the policy icon in EPO , it is trying to load a new one.
Try to uninstall the DLP Management tools v 9.3 from Control panel first , reboot and try to click the icon again inside your EPO.
When you open it with IE, it should prompt an activeX pop up asking to install the management tools.
