Install downloaded version next to existing version

Hello everyone,

Issue:
I installed my current version using flatpak (Citra nIghtly 1390), but antoher version would better suit my system (Canary Build d831d7c). I manually downloaded the archive with the folder \canary in it. I am unsure how to proceed.
Should I just overwrite the files I found for citra on my disk?
Is there .\install file I need to download separately?

Looking at building for linux references only the latest release downloaded and build from Github. I installed it via Flatpak, because I was not able to build a stable version using the instructions from the link.

System Information

  • Operating System: Ubuntu 16.04

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

‘Open log location’ is unable to open a file location. Also I do not have a problem with a specific game or setting. I do not think the log file will help
