Hi. Im having issues upon opening my Autocad. I already re-install Autocad LT 2016 but still the same i cant use it. I have 2 AutoCads in my PC, AutoCad LT 2018 and the one the im always using is Autocad LT 2016, the other Autocad LT 2018 is working but the 2016 version isnt. What can I do? See attached screenshot.
