For the User Environment Manager to run correctly, FlexEngine must run during the logon and logoff process. To run FlexEngine at logoff, you must run the FlexEngine logoff command from a logoff script. To run FlexEngine at logon, you can either configure Flex Engine as Group Policy client-side extension, or run the FlexEngine logon command from a logon script.

For information about how to run FlexEngine as Group Policy client-side extension, see Configure FlexEngine to Run as Group Policy Extension Setting.
