Hi:
I downloaded local wpengine version 6.4.0, after that when I tried to install it says local setup Installation aborted and the setup was not completed successfully. it won’t continue installation. any possible solution? TIA
Hi there, Ronald! Thank you for bringing your question to the Local Community. 
Have you tried running the installation again?
There is also a newer version of Local you can try - 6.4.1 - available here: Releases - Local
Let me know if either of those things help,
Sam
