pls help

win 8.1 64bit
ram 8gb
gtx 660 2gb

hdd 20 gb space for project and engine (alot ppl say that u need 5gb+ to bulid a light)

try disabling the any antivirus or windows firewall and defender and report back if the error message is still being displayed .

i did that nothing same issue

swarm

The service cannot be started, either
because it is disabled or because it
has no enabled devices associated with
it

try to

  1. Open UE4.sln
  2. Build UnrealLightmass

man the thing is I got to give U a bad news that I don’t really know what to do . I had this error occur and had it fixed in this way as I was not able to compile properly/build with the 12.5 version I downloaded using the launcher .but with the git version I faced this problem and fixed it in the way I suggested above . I can give U a few optional suggestions which U don’t need to follow strictly (your call)

  1. Try the github engine source code Install it in any other drive rather than C.Now if the same problem occurs then U might have a good chance of fixing it Urself .
  2. do a windows reinstall and try the download again . If the error is still persistent the it would be obvious that it either is a GPU issue or UE4 problem
  3. Wish U luck bro as I am totally out of suggestions for now.

****Totally a suggestion . U decide whether to follow or not .Also maybe there are chances that if u try the engine installation in a drive with more space U might have a good chance of running it .

I dont have ue4.sln is this ue4 source files?
But i have lightmass.exe already
btw i installed win7 on other partion
it’s works well bulding light no swark error
So no wrong with ue4 files so what the issue is it win 8.1 ?

thanks again and i hope bulding light mass will solve my issue :slight_smile:

Yeah sure hope Ur issue gets resolved . For the time being if this alternate way of using the engine works its OK . Keep learning and I think this issue has already been given some priority and as well I would recommend U using 4.12.5 its one of the versions I use . Surely do an update I stay active at the forum if U run into any difficulty during installing the source . But, I am afraid that the source file is not only 194MB in size . It requires almost 3.7GB of download to fully setup the engine . And U would surely require a good amt. of data speed to download the full engine

mmmm i don’t know i just download source from
https://github.com/EpicGames/UnrealEngine/releases
i’ll search for 4.12.5 in google or torrents maybe will works for me :slight_smile:
thanks A GUPTA

stupid qustion if i bulid ue4 from source will it have blueprint ? or conly c++

All the engine sources are provided at the github . U’ll just need to select the version U want to download…

Both options are available…
