After installing and configuring Search Server Express 2010 on Foundation I was unable to open the Search Service Application I had created in order to configure the crawling. To fix this problem you need to do the following.

  • Go To Central Administration
  • Under Application Management, click Manage Service Applications 
  • Highlight the Search Service Application Service that you can't get access to.
  • Click on Administrators in the ribbon
  • Add your account to the list of Administrators and then check the Full Control Check Box.
  • Click OK

Now you should be able to click on the Service Application and Administer it.

Hope this helps!
