State: closed
Merged: Yes

Describe your changes

Legacy NSIS installers (pre-0.70.1, before SetRegView 64 was added in .onInit) wrote their HKLM registry entries from a 32-bit process, so the writes were WOW64-redirected to HKLM\Software\Wow6432Node\…. Even older builds wrote the autostart entry under HKCU. Neither the current NSIS nor the MSI removes those legacy values on upgrade, so a user who installed an older NSIS and later runs a newer installer (NSIS or MSI) ends up with duplicate Run\Netbird values across registry views and a stale row in Programs and Features.

NSIS install and uninstall: also clean HKCU\…\Run\Netbird and the 32-bit-view HKLM Run\Netbird, App Paths\Netbird{,-ui} and Uninstall\Netbird.
MSI: new per-machine always32 component removes the same Wow6432Node entries on install; new per-user component removes the HKCU Run\Netbird value. Both use marker KeyPaths under Software\NetBird GmbH\Installer.

Summary by CodeRabbit

Chores
- Enhanced installer cleanup procedures to more thoroughly remove legacy registry entries and configuration settings left behind by previous versions. Both installation and uninstallation processes now provide improved cleanup across registry locations, ensuring better system cleanliness and preventing conflicts.
