Thanks in advance for your help. I am trying to get a copy of RS Logix Micro Starter Lite (Rev. 8.3) running on a Windows 7 laptop, connecting to a MicroLogix 1000 (1761-L32AWA). Everything is up and functional to a degree, but I cannot edit the program - if I try to use the icons for adding a rung or elements, it simply ignores the input, and when I go to to the pull-down menus, all of the options for adding elements are grayed out. The "ladder" showing communication is spinning, the tx/rcv leds on the USB cable are flashing, I can alter data such as timer and counter presets and bounce back and forth between run mode and program mode. When I use my ancient DOS-based Toshiba with the equally ancient MPS software, everything works fine. As far as I can tell, there is no activation process that allows full functionality. It reminds me of some of the old Honeywell PLCs that had a separate mode for limited access to data tables, but wouldn't allow the program to be tampered with, but I've never seen anything like that on the Micros. Thanks again.
