v0.3.4

What's New in v0.3.4

Installation Fixes

• setup.exe now requests elevation via UAC — fixes error 1625 ("installation forbidden by system policy") on devices where Windows Installer requires admin
• No more 7-Zip dependency — model extraction now uses built-in SharpCompress library. Works on locked-down devices (Grid Pads) without needing 7-Zip installed
• merged_models.json search paths fixed — resolves "No Download URL" error when running from an MSI install

Voice Engine Fixes

• Azure voice preview — fixed silent preview (Azure returns MP3, SoundPlayer needs WAV; now uses SynthToFileAsync with WAV format)
• Kokoro model type detection — voices.bin presence now correctly sets SherpaOnnxModelType=2 (Kokoro) in registry tokens
• MMS models — download individual files from HuggingFace directories instead of trying to fetch a directory URL (was 404)
• Download progress — streaming download with percentage, file size (MB), and throttled UI updates
• SherpaOnnx model promotion — uses .reg file import for fast, reliable elevation instead of relaunching the 116MB exe

SAPI Compatibility

• 32-bit registration — correctly checks WOW6432Node registry hive and uses SysWOW64\regsvr32.exe
• Grid 3 / System.Speech — model type-aware HKLM token promotion with SherpaOnnxVoices for Kokoro models
• HKCU voice cleanup — cleanup-voices.ps1 now covers HKLM, WOW6432Node, AND HKCU voice tokens

CI / Build

• Full CI pipeline — all 12 jobs green (C++ DLL, VoiceGarden.UI, CLI tools, .NET adapter, MSI)
• Release assets — MSI, setup.exe, per-platform ZIPs (x86/x64), debug symbols, full release layout
• DotNetTtsWrapper from NuGet.org — no longer clones from source during CI
