SharePoint Excel Error: Unable to Load WorkBook

When trying to open a excel file many come across this exception stating :

"The workbook that you selected cannot be loaded because it contains the following features are not supported by Excel Services"

Many blog suggested for Excel Services Trusted Site Entry for the excel file referring.

However the solution that worked for me:

Give "Read permissions" to the users and they will be able to open the file using excel client.
Steps :
For more info on how to see permissions you have for users and groups in your site go to: Site Actions > Site Settings > Advanced Permissions.
Edit User Permissions to Read

Also make sure the permission are inherited to the Document Library permissions.

Warning: Super user account!

When Working on a farm environment couple of time we come across some warning stating:
"The super user account utilized by the cache is not configured...."

Temporary Solution :: execute- 'stsadm -o setproperty -propertyname portalsuperuseraccount -propertyvalue account -url webappurl'.

Furthermore, there is the caveat:
The account should be any account that has Full Control access to the SharePoint databases but is not an application pool account. What have people done - create a special account?

After doing an extensive research i found solution as stated by Mirjam van Olst
