System SecurityException Request for Permission

Affected Software/Reports/DLL(s): EDP

Affected Software Version: N/A

Symptoms: When attempting to open or use a format file on a network drive, the following error occurs.

System.Security.SecurityException: Request for the permission of type

'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0,

Instance, Type Type, String MemberName

Cause/Details: The following error may occur for formats on a network drive, if the security policy is not configured.

Resolution/Workaround: In certain scenarios, clients may wish to store EDP format files on network drives. Often, the .NET security policy is not configured to allow assemblies from a network drive as described here: http://support.microsoft.com/kb/832742.

One option to resolve this error is to move all the files for the format (.xse, .vbe, .dll, .rvf, -enum.eml) to be located on the machine that is running EDP, not on a network drive.

Another option is to change the .NET policy to allow execution of the assemblies from the network drive.
