Cannot open input file UE4-Launch.lib

Trying to compile “Development” “Win64” version of my game and getting this error.

Error 4 error LNK1181: cannot open input file ‘C:\UnrealEngine\UnrealEngine\Engine\Binaries\Win64\UE4-Launch.lib’

Verified that the .lib file doesn’t exist. Any idea why it’s missing/what I need to build to create it? I don’t have any problem building “Debug” “Win64”. That compiles with no errors.

Answering my own question…again. Not sure exactly what sequence led to this, but regenerating the project files fixed the error.
