Go to the folder where you installed your Canary version of Android Studio (most likely in Program Files).
Go to bin folder
Open both studio.exe.vmoptions and studio64.exe.vmoptions in a text editor.
In that, change the following line -Didea.paths.selector=AndroidStudio1.4 to -Didea.paths.selector=AndroidStudioPreview1.4. Or to any other Setting folder that you want.
