I am contemplating changing my windows 7 pro to windows 10 OS. I’m not in a hurry to upgrade to LW 2019, but I’m experiencing not being able to open modeler, i think it could be an OS problem, and since Microsoft does not support win 7 anymore, i have doubts , there is an option I’ve heard that microsoft with allow an extention of 3 years more of support for windows 7 professional, at a charge im sure, i am leaning toward maintaining my windows 7 pro, and re- installing it to see if that corrects my issue of opening modeler, Layout opens fine, but will not open modeler , there seems to be a OS issue from the startup menu, also from the program directory, no go on modeler.
