Error building Admin Menus

[gilco]

Hi,

I'm using Joomla 1.6 and Jumi 2.0.6.

When installing Jumi I getvthe error "Error building Admin Menus" - the jumi component is missing from the components list, though "jumi application" is there on the list when trying to add a new menu item.
I tried re-installing several times with a fresh package - same result.

Can someone help me to see how can I install it so it will work properly?

Thanks,

Gil.
