Excel 2007 Ribbon Problem...

Hi Friends,

I've made two excel addins for excel 2007 version. When its load, automatically add a tab called utilities.
I want to know...

1.) Whether we can check its installed or not from vba code.
2.) If its installed then want to add some more group in the same tab.
3.) It its not installed yet, then create new tab called utilities.

I know how to add a new tab or add commands in an existing tab, but I'm not able to check for existing tab's load status


When i load my first addin its working successfully, but when i installed the second addin its make an new tab with the same name.

I've attached the demo of ribbon tab (Utilities) for both addins:

I want to add in existing tab.

Any help on above will be appreciated.

And at VBAX http://www.vbaexpress.com/forum/showthread.php?t=42013
