I have a question in that has been asked in the answers section of the website though no help here,
Hello I am a new user to your engine so I am sorry for my lack of knowledge I am in the first attempt in building a level for a game that I will be working on and learning (from youtube, UE vault, friends) when I save the world that I am working on I save everything, compile when I want to see what the level is like I first run the project. it tells me there are 123 un-built lighting that needs to be done. looking into this I can see that there is a build function. I click on this and await for the process to complete.
this gets to 100% and then just hangs, I have tried to see if there is anything on my end that is the issue (RAM, HDD space). Just before you ask I am running 64Gb of 1800 speed ram and I have 6.5 Tb of hdd space out of this there is 5Tb of space free.
I let the build to complete (never happened) for 7 hours when I went to sleep. still there at 100% and not doing anything I couldn’t click on the stop nor could I exit the editor. I had to go into the Task manager and then end the process that way. when I re-launched the engine after I reset my computer I went to load the game again and added the information that was missed. again tried and again same issue.
I have uninstalled the version that I am using and reinstalled, and also uninstalled the launcher and reinstall. nothing worked and I am at a loss on what to do.
ok, I have gone onto my laptop and tried this again, I still get the same issue 
Since I will be using my laptop more and more, and I some how broke my screens I will be using this on my laptop I have also save my dxdiag here for you to see.
So I have read that you need to fix the swarm agent, I have done the delete and install of SDK v8.1 and also for windows 10, this hasn’t fixed my issues and I have also fixed my .net as well and downloaded the up to date drivers for this as well and again no fix. I have also deleted the swarm log in %appdata% again no fix. please help
Now I am getting build scene not saving as well as Spawn no going past the 100% on this as well. Am I destined to not do this game with UE4?
Warning high text Swarm works on my laptop and I get this when I open up the launcher:
