MailSentinel Client

This page only downloads the current MailSentinel Client installer. The installed Windows client handles local launch, user data, and future A/B updates.

If the installed updater fails while replacing Runtime\slots\b, run this installer once. Older updaters cannot repair that locked fixed-slot state by themselves.

Checking current version...

Update source: clients read /version.txt first, then fall back to /updates/windows/current.json for package details. This bootstrap reads the manifest for installer downloads.
