For the odd computer here and there I’ve had LEGO Mindstorms get stuck on the splash screen (we’re talking 10-15 minutes or more). A bit of trouble, but I’ve found going to /Library/Internet Plug-Ins and deleting the Silverlight.plugin, then reinstalling both Silverlight and LEGO Mindstorms seems to fix it.

I had the same problem with my Windows 10. I re-installed Silverlight 64 bit and it did not fix the issue until I installed Silverlight 32 bit. Here is the link for Silverlight 32 bit.
