If the engine is crashing are you getting a Crash Reporter Window or just a generic Windows Error and the editor closes? If the latter, can you look at this Windows Event Viewer Wiki and post the event logs from that crash as the wiki explains and I will try to help you out?

When it crashes there is no message. Not from unreal crash reporter… not from windows… nothing… its just poof where did unreal go… and i hit ctrl alt delete the unreal editor exe isnt even there… which is very odd…
I recently switched the coordinator to this computer that is having the issue… when i went to 4.10 i switched the coordinator to the one that is runnign the edtior… and this magic crash happens (I THINK) when the coordinator running… otherwise if i try to do the build alone it just says build failed with no crash.
I will look through your link.
Oh and the build does not fail if i build on my computer at my job (which is a much worse computer) So it has to be something specific on that computer at home…
Not sure if this was what your looking for with the crash reporter but i tried to follow instructions from your link. I selected multiple crashes.
That was it exactly. I am going to dig through those event logs and will post back as soon as I have additional information.

Initially it looks like there is some conflict between 32 bit and 64 bit software that is occurring. So to test, if you can go into your Engine Installation Directory (by default it is Program File\Epic Games) 4.10\Engine\Extras\Redist\en-us\ and run the UE4PrereqSetup_x86.exe file. This file will install 32bit VS2015 Redistributables which may solve the issue, let me know.

Ill give that a try, but does that somehow mean i wont be able to take advantage of 64 bit ? I mean my comp hardware specs and os are way up to spec.
No your PC will still take advantage of 64 bit processing, but Swarm is built on 32 bit DotNET Framework, your computer will still run it, just some prereqs may not have been installed based on most of your CPU not needing the 32 bit - 64 bit communication.
Tried that… still didnt work. Same problem.
Though that being said… it could be 2 problems were looking at that are different. 1 crashing if trying to network a build… or 2 build failed if the comp is alone with no crash. So far alls im testing is build failed… since there is no point in coordinating if hte 1 comp fails.
Oh yea and i did notice something else interesting. If swarm agent is already running in the background started up on its own… it says failed to connect to swarm instead of build failed.
I am attaching a screenshot of what .net framework versions are installed. I was reading at the following link something about installing another version… is this something that it looks like i should try??
Yes I have tried the validation in launcher via verify.
I have tried both ways. 1.) letting swarm launch itself when i click build … and 2.) starting swarm on its own before i even start the editor.
Yes its 4.10. Triple checked that. I dont even have any other version installed anymore. But yes I have confirmed the directory and made a new shortcut for it.
Yes I have tried to clean and validate swarm cache inside swarm agent with its menu.
UE4PrereqSetup_x86.exe is the one u asked me to install so I have. Not sure if you want me to install anything else.
I am not home to try that command yet, but to verify did you want me to run it on the computer that fails the build? Or the work computer that at least starts running the build correctly? Or both?
Hello -
To Confirm what we have tried so far, You have ensured that your Engine Version is validated via the Launcher. If you are starting Swarm at Startup (not just starting it when you build lighting) that you are running the 4.10 version of the Agent. That you have cleaned and validated your Swarm Cache. You have installed all VS Redist Prereqs.
Now based on the issues you are describing here and in your other Swarm related HLOD question, it sounds like there is a conflict or setup issue with one of the VS Redsit or another program. To best get a handle on what might be going on I need to know exact what you have installed and what version it is.
Can you please open a Command Window as an Administrator on the PC that looks to successful build lighting but the Build Failed Message comes back and run the following two commands:
WMIC [ENTER]
/output:C:\SoftwareInventory.txt product get name,version,installlocation,installdate,vendor,description,installstate [ENTER]
This command will output a Software Inventory on the C:\ drive of all your installed software on the PC. Because of the nature of this file I would like you to send it to me via Private Message on the Forums. There is no really sensitive information generated by this command, but I like to err on the side of privacy.
Thank You

You should also try to install UE4PrereqSetup_x64.exe found in the same place. If it pops up with a window just to uninstall then it has been installed already.
Thank you for confirming that I just want to make sure that I had covered some of the “Is it Plugged in” possibilities.
If you can run it on the Computer that fails to build first that is the one I want to focus on first.
Thank You Agian -

Yea I tried the x64 as well on my own… and it was already installed.
Thanks for the help. I will try that command when i get home in like 4 hours or so.
Did you see that .net frame work screen shot i sent u… i saw something on the forums of isntalling .net4.5 to fix something? Is that something i shoudl try…?
I do not know how to make that command work… when i hit enter it says Invalid file name.
update
Nevermind … for some reason it wont create the file on drive C… in fact i need admin privelages just to paste a file into drive C which is odd… Apparently windows 8 doesnt allow you to create any files on the root of your drive C…but i used another hard drive to generate the file instead. I have sent it to you in the unreal forums.
Hi Eric, I have been doing more tests on my end. As you know my “REVY” machine will not build… its a windows 8.1 comp with 4 ghz i7 and gtx 980…
My work computer which is a windows 7 3.5 ghz i7 and a gtx 590 was able to start a build but windwos complained about memory or something an hour into building and apparently shut down the edtior… its a 12gb ram computer… but it failed… who knows…
NOW… i just tried my laptop which is a 2.5 ghz i7 with gtx 980m… And it crashes unreal completely with my project… or with your simple test project it has the same problem as the “REVY” computer… The build failed error… This computer is also on windows 8.1…
I also just tried my windows 7 2.7ghz i7 with a gtx 780… That also went to lighting build failed…
Dude im really at a loss…i cant build any project on ANY COMPUTER it would seem. So far 4 computers have not been able to build… 3 of which i tried with your simple scene… How do bugs this monumental that are total show stoppers slip through your guys QA process??? This just hurts me … i already dumped a lot of money into this project… and now were stuck…
Wow I finally solved the build failed problem, though the networking computers to build together problem still exists… they all work together, but motoko doesnt reach the blue bars, and Rock seemed to reach the blue bars one time… but then the rest no… its odd…
The build failed was fixed by disabling the “run as administrator” checkbox in windows on swarm agents exes… I had apparently set that to see if that would make the networking build work correctly.
Hello -
I found this link on our Forums while doing some research on Swarm Agent and Coordinator and I think it explains why your three CPUS are not running constantly in Coordinator.
From that post it sounds like the guys otehr computers arent being used… as though that are saying available but not being used for the build process… or maybe im misinterpreting…
In either case…Heres the thing… Revy is always the one who launches the build process regaurdless of which computer is the coordinator… motoko or revy. Revy will always function correctly… The other like motoko will never reach blue bars ever… and Rock will maybe reach it once , but then continue ot other orange /grey bars… but wont reach blue again…
In the past this scene (which has only gotten more complicated) would take advantage of 3 computers… All doing things in the proper order… Grey, Red, Orange, and finally blue… All machines would do this…
This is all odd behavior to me where the one doesnt even make it to blue at all…And this does not appear to be speeding up the build process from one computer doing it alone… (though i have not verified that.) Is there a way to see how long a build process took?
And another thing… as to that response… he says that each computer would finish processing its mappings and then see if there is more to do… The blue bar is “processing mapping”… so it just never gets there. At least thats what it seems like unless im wrong. just seems like a waste to buy all these machines for this engine and then not be able to coordinate…
Oh and plus that doesnt explain all the “failed” error messages inside the log for swarm.
Hi ERic,
cleary that link you sent me too has nothing to do with whats happening here.
I did another test with just 2 computers… For one… it took the same amount of render time exactly as the previous builds. For two… the motoko computer never reached the blue bars… and only went to the other colored bars 1 time… see the screenshots.
Its been a long time since i originally asked the question and still no where near closer to finding an answer… Is there anyone else you can talk to on this? because you yourself may not have the knowledge necessary of this thing. No offense… but months are going by here without an answer…
Please dont accept answers that are not the answer to the original problem.
I am still awaiting an answer to make all computers build together… and not just start together.
