Hello,

First of all, thank you for all the great work you are accomplishing at Proton.

I really love the idea of using Proton via the desktop app, but one thing is a no-go for me :

My disks are partitioned and my OS is isolated from my other installed applications.

I don't want ProtonMail client to be installed in "%LocalAppData%\proton_mail" by default and wanna be able to choose another partition / disk to install it.

I investigated a bit on the underlying installation system, which is Squirrel, and actually it seems to not allow installation path customization.
https://github.com/Squirrel/Squirrel.Windows/blob/develop/docs/using/install-process.md

Don't know if there is an hidden feature in Squirrel for this, or if the installer/packager technical stack could/should be change to allow custom installation path.

I really hope you'd be able to address this issue, as I really want to switch to ProtonMail desktop app.

Keep up the great work !
