BPC Excel Plaaning and consolidation Tab missing

I have installed BPC client 7.5 SP 5 patch 5. On Excel Planning and consolidaiton tab is missing.

When I check Excel Options Add-ins menu "Planning and Consolidation " is under Inactive Apllications. When I try to activate with COM Add-ins I receive the message " This add-in is installed for all users on this computer, and can only be connected or disconnected by an administrator" and cannot activate it.
