Use Windows 11 x64 with Microsoft Edge WebView2 and Microsoft Defender Antivirus. Download and extract the complete setup ZIP. In a terminal opened in that folder, run:

.\FetchVolt.exe --install

Version 2.6.1 opens a setup wizard with the license, installation folder, Start menu shortcut and terminal-command options. The wizard installs for your Windows user and does not require PowerShell 7. For scripted installation, use --install --silent --accept-license only after reading and accepting the license.

Keep the default installation folder for fetchvolt update support. Custom folders work, but updates require running the newer executable with --install again. Applying terminal updates requires PowerShell 7 on PATH; checking for an update does not install it.

The included Install-NetBooster.ps1 script remains an alternative for PowerShell 7 and offers optional browser setup. Follow your Windows execution policy. From the app, open Settings → Browser extension to prepare the optional Browser Link files.

For Edge or Chrome, open the browser's Extensions page, enable Developer mode, choose Load unpacked, and select the folder shown by the setup guide. Open the extension, check the app connection, and explicitly turn handoff on. Store publication and Firefox signing are still pending.

Close the app before updating; you do not need to uninstall first. To remove it, use Windows Installed apps or fetchvolt --uninstall. Remove Browser Link from each browser separately.

Use an existing local output folder. The installed app bundles its local MCP server. In FetchVolt, open AI & MCP, prepare the server, enter the output folder and copy the displayed host configuration into your compatible MCP client.

The server exposes list_connections, start_download and download_status over local stdio. It allows public HTTPS URLs, limits concurrent work and prevents overwriting existing destination files. Grant access only to a folder you intend the AI to use. AI software providers have their own privacy terms.

Compatible range downloads retain completed, verified chunks. Choose Save progress and close, then resume from saved progress when you return. A changed ETag, changed file size or unsupported server can prevent recovery. Single-stream downloads may need to start again.

In the app, open Network and choose Test your connection. Select an adapter and start a bounded sample of up to 10 MB (9.54 MiB) of download payload, plus network overhead. The test contacts Cloudflare, which receives your public IP under its privacy policy. It never runs automatically.

Results describe receive throughput and HTTPS response timing on that one path to Cloudflare. This is not an upload test, ICMP ping, or a promise of combined download speeds. Short samples and other traffic can affect the result. Only the five latest successful tests remain in memory for the current app session. Test payloads are discarded without being saved as files.

FetchVolt 2.6 adds a command to your Windows user PATH. After installing the setup bundle, open a new terminal:

fetchvolt --version
fetchvolt connections
fetchvolt update --check
fetchvolt update --check --json

Ready to install a newer release? Save your downloads and close the app, then run:

fetchvolt update

Applying updates requires PowerShell 7, available as pwsh.exe on PATH. Checking for updates leaves the installation unchanged. Updates come from published FetchVolt releases; a source commit alone does not update your app.

The updater verifies publisher-signed metadata and file hashes, then requires a clean Microsoft Defender scan before replacement. Settings and recoverable download data are retained. If you have version 2.5 or earlier, install the current setup bundle once to get the terminal command. Run fetchvolt --help for command help.

The app validates HTTPS certificates, bounds transfer work, preserves existing destination files until publication, applies Windows Mark of the Web and asks Defender to scan the staged file. Browser and MCP requests additionally require public endpoints and cannot disable these checks. No downloaded file is executed automatically.

These protections reduce risk; they do not guarantee that every file is harmless or that software has no vulnerabilities. Respect Windows warnings and keep Windows, Defender and your browser current.
