If you already have SQL Search installed, and you install a new version of Management Studio, SQL Search won't appear in the new version of Management Studio.

To use SQL Search in the new version of Management Studio, you need to repair the SSMS Integration Pack Framework installation:

1. Open Programs and Features. 

2. Right-click SSMS Integration Pack Framework 1 and select Repair.
   
   

You should now be able to use SQL Search in the new version of Management Studio.

If SQL Search still doesn't appear in Management Studio after repairing the SSMS Integration Pack Framework, uninstall SQL Search and the SSMS Integration Pack Framework 1 and then reinstall SQL Search, which will also automatically reinstall the SSMS Integration Pack Framework 1.
