Managing user access rights
When the Genero Application Server starts an application, the user needs to have rights to execute the DVM and access any needed program files and resources.
The 
        fglrun process executes in the context of the operating system
                user running the Genero Application Server. Generally, this is the user running IIS
                when using the ISAPI connector or the user running Apache when using the FastCGI
                connector. You must ensure that a user has the permissions needed to:- Execute the DVM 
fglrunprogram - Access any needed DVM resources (ODI add-ons, configuration files, and so on)
 - Access any needed program files and resources (42r files, 42m files, 42f files, and so on)
