old search page opens in 11.0.1 instead of new search page

Hi,

After upgrading a customer from version 10.0.4 to 11.0.1 and installing the new client on the customer machine the following happens:

1. in EV ribbon - when pressing "search vault" button - search opens in new IE page and not inside the outlook window.

2. the search page that opens is the old search.asp page, when i remove the .asp from the address, new new search appears and all searches are working, but it wont open as the default search page.

Anyone seen this before? 

how can I force the search page to:

1. open inside outlook

2. open the new search page.

Thanks,

Sarah
