Alright Guys, Thanks for that info....
So I can run two instances at once, and so my next dumb question is;
do they have to have different names, or does the fact they are running from different folders separate them?
If they need different names, what am I renaming? the AdvancedHMIv35.sln, or the MainForm.vb, or is it something else?
Regards,
