I have Sharepoint 2010 Foundation with Search Server Express installed. The Sharepoint was an upgrade from WSS v3 and search server express 2003.
After the upgrade whenever users search from the main site I get web part errors displayed on the search page. I think because it is trying to use the old search server express which is no longer installed.
Search Server Express 2010 is now installed and a Search Center web page can be viewed however when searching via the entire sites I site the web page with web part errors.
Any thoughts or any further information you require I can provide.
