# Install Geo Sender

## Download

Use the official latest installer:

`https://github.com/visi-digital-internasional/geo-sender/releases/latest/download/GeoSenderSetup.exe`

## Installation steps

1. Download `GeoSenderSetup.exe`.
2. Close any older Geo Sender window.
3. Run the installer.
4. Accept the Windows prompt when the installer source is trusted.
5. Complete the setup wizard.
6. Launch Geo Sender from the Start menu or desktop shortcut.

## Upgrade an existing installation

The installer uses a stable filename so it can replace the existing installation during an update. Your normal application data should remain available unless the release notes explicitly state otherwise.

## Verify the download

Each release includes a SHA-256 file. Advanced users can calculate the local installer hash:

```powershell
Get-FileHash .\GeoSenderSetup.exe -Algorithm SHA256
```

Compare it with the hash published in the same GitHub release.
