Hey guys, 
 if you receive the following Exception if you try to open the sample workbook or another workbook try the following steps: 
 
1. Open Central Administration -> go to Operations tab 
- ensure that the Excel Service is running
 
2. Open Central Administration -> go to your configured Shared Service -> click Excel Service Settings
-  File Access Method:  ensure that it is not using Impersonation, instead the Option Process Account should be enabled.
 
3. Open Central Administration -> go to your configured Shared Service -> click add new trusted file location
- field URL: here you can specify a report library or the whole portal
- Location Type: should be Windows SharePoint Services
- Children trusted: defines whether the children should also be trusted or only the definied path
