Download Dual Internet
One signed installer, no bundled extras. The 30-day trial starts the moment it finishes — no key, no account, no email required.
Installer for Windows
Authenticode-signed MSI, per-machine. Installs the application and a Start menu shortcut — nothing else, no service and nothing added to your PATH. Elevation is requested once during install and once per launch, because routing needs it.
Download for Windows — 18 MBx64 build. Want the checksum first? See all files.

Format-List Status, SignerCertificateSmartScreen may warn on a new release
Reputation accrues per signed build, so the first few days after a release Windows may show "unrecognised app". Confirm the signature says Valid and the signer matches, then choose More info and Run anyway.
Before you install
System requirements
Operating system
Windows 10 version 1809 (build 17763) or newer, or Windows 11. Windows Server 2019 and 2022 work but are not part of the test matrix.
Architecture
x64. There is no 32-bit build — the filtering-platform work needs a 64-bit host process. An ARM64 build is not published yet.
Privileges
Administrator for routing. Monitoring, speed tests and diagnostics run unelevated with routing disabled.
Runtime
None to install. The .NET 8 runtime is bundled inside the installer, so nothing else is required first.
Disk
About 120 MB installed, plus the local SQLite database — a few MB per month of history at default retention.
Network
Two or more adapters with their own gateways for routing to do anything. One adapter still gives you full monitoring.
Antivirus software occasionally flags filtering-platform registration. If a scanner quarantines the service, the troubleshooting guide lists the exclusion paths.

The installer and its checksum file. Verify before you run it — the command is below the table.

No portable build
There is no unzip-and-run version. The application needs Administrator rights to register filtering-platform filters, and a per-machine install is what makes the elevation prompt name a real publisher rather than an unknown one. If you cannot install software on the machine, this app cannot do its job on it either.
Silent and unattended install
msiexec /i DualInternet-1.0.0-win.msi /qn ^
/l*v install.logBoth properties are optional. Enterprise deployment notes, Group Policy and Intune templates are in the deployment guide.
