HMI mer file problems

I am trying to download a old copy of HMI program to HMI. I open the MER file and a image of main screen comes up in factory talk. However I have no explorer window so I can’t make changes. Why is it doing this ?


  1. open the application manager and restore from the .mer to make changes in the studio.
  2. In the photo it seems that you do not have communication with the plc.
