Welcome to Seven Forums Mies07. you can try this but I don't know if it will work, I use nothing Google on my PC.
In Internet Explorer>Tools>Manage Add-ons>Search Providers. If Google is not there to set as a default, go to Find Search Providers at the bottom of the window and find Google Seach on the site that opens. Download it and then try to make it show as a toolbar in the systray.
