When trying to browse the performance overview tab in the vSphere client you may get an error stating “This program cannot display the webpage” but at the same time, however, the advanced tab works fine.
Luckily, as vinf.net point out, this is pretty simple to fix. The cause of the problem is that the VMware Virtual Centre Management Webservices service is not running on the vCentre management server.
To fix the problem simply re-start the service manually on the windows server that has the vCentre management software installed on it.
