im trying to upgrade a project to 4.11. i can run 4.10 just fine. And 4.11 works on my desktop. but for some reason when i try to launch 4.11 on the laptop it gets to 75% and then just stops. Anyone know why that could be happening?
I’ve had this happen several times. I don’t know why it happens, but for me most of the time just quitting and launching again would get past the freezing point. One time when it always froze at the same point I ended up making some modifications on my desktop and then the modified project would open on my laptop. Frustrating workarounds, I know. Good luck!
How did you change the version? Did you right-click your project file and switched engine version or did you try to open it in using the launcher and it asked you if you want to make a copy?
Hi ViceVersa,
Try opening the .uproject file direct from the \Unreal Projects\PROJECTNAME\ filepath instead of through the launcher. Do you see the same error? If so, can you post your dxdiag here so I can take a look?
Hi ViceVersa,
We have not heard from you in several days. I am marking this as answered for tracking purposes, if you are still experiencing this error, please comment with the requested information.
sorry i forgot about this. I think it had something to do with the substance plugin. When i got home i reinstalled it and updated the substance plugin, now everything works fine.
In that case, it sounds like my answer (restart stuff) was the closest to your actual solution. You should go hit the checkmark next to it.
