Here some notes about things to consider with Windows 7

File and Path Sharing
Unlike other versions of Windows, in your simulator network you will have to make sure all machines are running with the same access credentials. I.e. same Windows account user name and password. Please also check that the network sharing is set to ‘simple file sharing‘.

Program Permissions
Depending on your general configuration, you might have to make sure that the executables are set to ‘run as administrator’.  To set this, right-click on the executable (e.g. FCU.EXE) select ‘Properties‘ and then the ‘Compatibility‘ tag. Make sure the Privilege Level is checked and the program is allowed to run as an administrator.
