Pro Internet Downloader

Pro Internet Manager (by Triwar Design) is a fast, modern download manager for Windows. It downloads regular files and videos from sites such as YouTube, and picks up links straight from your browser with the "Pro Internet Manager Bridge" extension. Downloads (installer and portable zip) are on the Releases page. The source code is in this repository for viewing (see Source code and License).

What it does

• Downloads files and videos (video downloads use yt-dlp and ffmpeg, with a bundled JavaScript runtime, so you never have to install anything yourself).
• Browser extension for Firefox and Chromium browsers (Chrome, Edge, Brave) that lists the downloadable sources on the page you are on, with type and quality.
• Download queue with progress, speed, time left and size, plus a scheduler.
• Four themes (Pro Lime, Midnight, Graphite, Azeroth) plus Paper and Compact.
• Closes to the system tray and keeps running in the background. Right-click the tray icon to open it or exit.
• Built-in update check under Help, with automatic patch updates and rollback if something goes wrong.
• A real log file so you can see why something failed.

Screenshots

Note: all data in these screenshots is demo data: sample files, sample download states and sample statuses (for example "Bridge not connected" and the preview update prompt). The screenshots show the look of the app only and contain no relevant information about how the program itself works.

After an update, the app shows once what changed.

Install

Download the latest version from the Releases page. There are two options:

Installer (recommended): ProInternetManager-<version>-Setup.exe

• Run it and follow the steps. The default location is C:\Program Files\Pro Internet Manager (Windows asks for administrator permission once).
• The browser extensions are optional components: the Chromium extension (Chrome, Edge, Brave) is placed as a folder, and the last screen links to the signed Firefox extension.
• Adds Start menu and desktop shortcuts and an entry in Installed apps, with an uninstaller.

Portable zip (alternative): ProInternetManager-<version>-portable.zip

• No installer: unpack the zip to any folder and start Pro Internet Manager.exe. yt-dlp, ffmpeg and the JavaScript runtime are included.
• Close a running Pro Internet Manager first (also from the system tray).
• Settings and logs are stored in %APPDATA%\Pro Internet Downloader, the same place the installed version uses.

Source code

Folder	Contents
app/	The app (Rust, egui): src/, Cargo.toml, Cargo.lock, build.rs, build-restyle.bat, icons in assets/
extensions/firefox/	Source of the Firefox extension "Pro Internet Manager Bridge"
extensions/chromium/	Source of the Chromium extension (Chrome, Edge, Brave)
installer/	Source of the Windows installer (InstallerPIM.cs, C# / WinForms) and its build script build.ps1

Build the app (Windows):

1. Install Rust (stable, MSVC toolchain, via rustup) and the Visual Studio Build Tools with the Windows SDK.
2. cd app and run cargo build --release, or run build-restyle.bat, which builds and copies the result to Pro Internet Manager_restyle.exe (log in build.log). Optional variables such as VCVARS, PIM_SDKROOT and CARGO are described at the top of the script.
3. yt-dlp, ffmpeg and Deno are not in this repository. Put yt-dlp.exe, ffmpeg.exe and deno.exe next to the built exe.

Update source: the published source contains placeholders for the update links (https://example.invalid/...), so a build from this repository does not find updates. To use your own update source, set PIM_VERSION_URL (link to a version.txt), and optionally PIM_FALLBACK_VERSION_URL and PIM_DOWNLOAD_URL, as environment variables when you build. The official releases have their own update source.

Build the installer: run installer\build.ps1 in PowerShell after building the app. Put yt-dlp.exe, ffmpeg.exe, deno.exe, FFMPEG-NOTICE.txt and YT-DLP-NOTICE.txt in installer\payload-src (or set PIM_PAYLOAD_DIR). The background picture of the official installer is not included; without installer\assets\background.jpg Setup uses a plain background.

Patch notes

0.2.5

• Fixed the app showing "Bridge not connected" while downloads from the browser extension did arrive. Pings and downloads from the Firefox and Chromium extensions now both count, and the status stays "Bridge connected" while the extension is active.

Patch notes of older versions (0.2.0 to 0.2.4) are in PATCHNOTES_ARCHIVE.md.
