EV3 software used to work on my laptop. Now it does not load any more. When I double click on the LEGO Mindstorms icon. It starts the procedure of loading the software. Then it stuck there and won't go further. I tried to remove the software and reinstall it. Nothing helps. Has anyone else got into this problem before?


A possibility is, that you lack the latest Silverlight update.

I had this problem on some Windows and Mac OS X machines recently.

Maybe you can try to install the latest version: https://www.microsoft.com/silverlight/ I think it's worth a try.

  • I actually have the latest version of silverlight on my computer. :( Thank you for helping.

    Have a look at C:\Users\<User>\AppData\Local\LEGO\MINDSTORMS EV3\crashreports\ if there are any files (crash reports). This path may be a little bit different on Windows 8. This example is from Windows 10. Nov 29 '16 at 20:14
