NativePrep 1.0.5-beta.3 — Windows beta installation

Download only from https://github.com/OlehPoberezhnychenko/nativeprep-releases/releases/tag/v1.0.5-beta.3
Windows x64 is required. The engine is bundled; Python, Node.js and Rust are not required.

INSTALLER
Close NativePrep before installing or updating, then run the setup EXE.
The beta is unsigned, so Windows may show a publisher warning. Verify the source
and checksum before deciding to run it. Do not disable your antivirus.
If installation reports a locked DLL, cancel, close NativePrep and its engine,
then retry. Do not skip a required file.

PORTABLE ZIP
Extract the entire ZIP into a writable folder, such as Downloads\NativePrep.
Open the extracted folder and launch local-prep-studio.exe.
Keep the binaries folder beside the EXE. Do not run directly inside the ZIP.
WebView2 Runtime is required by the desktop shell; an unmanaged Windows machine
may need the Microsoft runtime installed before the application can launch.

FIRST TASK
Start with built-in sample data or copies of your files. Run a sample pipeline,
inspect its preview and export the result. Save your project for reuse.
Keep original files and project backups while evaluating the beta.

LIMITS
The import cap is 1 GiB per file. CSV and Excel imports can require substantially
more RAM than file size. Installation, upgrade and uninstall on a separate clean
Windows machine have not yet been verified.
