Hi, no way. Mixed manufacturing environment... Maybe it is hard to imagine, but our newest manufacturing machine (bought this year) is using Windows XP as control-unit and has to be integrated with the network. Which is the highest supported version of KSC/KEC for work with XP/2003? Microsoft is for us too fast with product life cycle 😬 But I hope, there is a very simple trick to mark the database as obsolate or corrupt and perform the update. If standrard repair from KES does (set very old database), it should be not to complicated.
