Unreal engine

If I start a new project using unreal 4.13 and try to open it on my personal computer using 4.11 would it still work because I'm having trouble trying to open up my scene?

New versions wouldn't work on old engine as far I know, only the other way around, opening old versions with a new version.

If you right click uproject file and select Switch engine version... does it help?

If you hover the mouse over your projects in the Epic launcher it will notify you what installed versions of the engine the project is compatible with.
