I have downloaded 10 different versions. The only one that kind of loaded was the first... And it only showed me the cura logo... When I clicked on it it disappeared and left me in the same boat. I am starting to think its a compatability issue or security issue not allowing it to load but I have no idea what it could be. This computer was bought maybe two years ago. It was a custom build and it was supposed to have solid performance for any of my work needs. 8gig of ram. 2 terrabytes of memory. I am not sure about the graphics card but how advanced does it need to be? I have used slic3r for years with no issues. I went looking for some kind of firewall and I see nothing that indicates it is being blocked but the program will not load. I sent a compatibility error off to Microsoft. A lot of good that will do. I am grasping at straws at this point. I really want to use this as Lulzbot has a bunch of predetermined settings for different quality prints and I have been having issues with one of our printers. I was hoping this would solve it. Anyway that is the end of my rant.
