Commented Unassigned: Access denied to temp path [11801]

Receiving and error when reading from stream. Access denied to temp path....? It happens when calling this method ExcelReaderFactory.CreateOpenXmlReader.
Obviously if I'm an admin on the box I dont get the error, but this is not realistic to a production site. Any thoughts?

Thanks

Maybe too late but I fixed the problem using the SPSecurity declaration:

SPSecurity.RunWithElevatedPrivileges(delegate

// here your code

)};

Hope it can help somebody else ;)
