SIMOTION P320-4: Why are the keys for Restart, Terminate, etc. grayed out and can no longer be operated?

  • Entry

For SIMOTION P you need the setting "Never report" of the user account control.

With the setting of the User Access Control or UAC you can define in Windows 7 for which actions that require administrator rights a confirmation is necessary. For SIMOTION P you need the setting "Never report".

Sometimes installation programs (the IPC Wizard, for example) make changes to the security settings of Windows and change the setting of the User Access Control.
Therefore, after installing programs or updates, you should check the setting of the User Access Control and, if necessary, reset it to "Never report". 

If "Never report" is not set for the User Access Control, the keys for Restart, Terminate, etc. are grayed out and can no longer be operated.

Further information about the User Access Control in Windows 7 is available, for example, in the Microsoft Support
