Post 26.05 Improvements to Portable Installation on Windows

Is your feature request related to a problem? Please describe.
Portable installation flow on Windows could be smoother as current methods are not well documented.

Following the method to extract the 26.05 msi from closed issue #4813 at

suggests using

msiexec /a drive1:\path\to\msi /qb TARGETDIR=drive2:\path\to\extract\folder

from https://superuser.com/a/307679

produces 2 files

  • anki-26.05-win-x64.msi
  • PFiles64
    • Anki

Describe the solution you’d like
Clearer documentation is always welcome, but it seems that Briefcase supports user defined custom install locations other than the 2: this user and all user options.

On Beeware’s Briefcase Github

and under features on release: 0.3.26 (2025-12-04)

mentions: Windows MSI installers now provide the option for users to configure the install directory for apps. (#2553)

So if a user can define the folder to extract at install time, extraction would be more intuitive

Describe alternatives you’ve considered
I have not tried alternative ways to unpack the msi and run anki portably.

I have used the msiexec /a path1 /qb path2 method to install to flash drive and followed current documentation to run anki portably with no issues so far.

Thanks in advance for reading and the team did a great job with the release this week!

I suggest adding a text box with a default install location like how the installer for 25.07.2 worked if briefcase allows. If that is infeasible for technical reasons, documentation update would be greatly appreciated and a zip release for year or month releases in year.month.patch would work as well though less ideal.

Any thoughts?
