VibeFuse v0.1.42 fixes Settings → About → Update.
What was going wrong
The Update button downloaded `VibeFuseInstaller.exe` and counted progress by reading that stream before the file was saved. On a fast connection those bytes were consumed first, so the saved file was empty or missing the Windows executable header. The button then stopped with “Downloaded file is not a Windows executable.”
What changed
Progress is counted on the bytes as they are written. The saved installer keeps its `MZ` header and can be launched.
Get it
This installed copy still has the old download, so use fuseintelligence.org/downloads/VibeFuse/ once and run VibeFuseInstaller.exe. Later updates can use Settings → About → Update.
