PackagingResults:Error: Error Launch failed! Unknown Error

Hi ,well i was trying to launch my “game (alt+shift+p) and a few seconds later i recived that message "
PackagingResults:Error: Error Launch failed! Unknown Error”…i tought maybe something that i added to my game so i started a new proyect (third person) and launched again but the same error appears…any ideas??

Thank you all for reading.

Good way to go, paste the log here :slight_smile:

i searched for this trouble but didnt find that post thanks mamoniem ill try that solution hope it works. :slight_smile:

edit: i tried the solution there downloaded the “Streams.exe” but donts sems to work or i dont know how to use it any ideas? btw im using the blueprints project not the c++

Edit edit:well i downloaded the 4.9 version and works just fine i can execute the game without any trouble looks like its because of the “AutomationTool” but i dont know how to fix it…i tried the DLL solution downloading the program but didnt work and when i left-click on the dll files dont show the “unblock” button (looks like its unlocked)…any ideas?? thanks all for the time

Solveeeed…for all the ones who are having the same troubles ,and like me, like the free stuff from the market (i know i know ill start paying for the stuff its better than a headache XD) watch out because my problem was caused for the “substanse” plug in…thanks all for reading and mamoniem for the answer!

Thanks so much for taking time to write solution! I disabled substance plugin and now my works as well! :slight_smile:

Yeah, but if you want to use SBSAR materrials, then use B2M to encode them as JPG Texture Maps
