SPT Launcher

A native WPF launcher for SPT (Single Player Tarkov) with Fika co-op support.

Features

• Play-first Launcher — Launch / Stop up front, with a compact readiness checklist for SPT, live Tarkov, and Fika
• Guided first-run setup — Install SPT first, then auto-detect or browse for SPT.Launcher.exe (including modern SPT_Runtime installs)
• Safer SPT updates — Preflight checks, download details, cancel, installer-only mode, and backup/restore recovery
• Live Tarkov / patcher awareness — Detects your live EFT version and checks the SPT patcher CDN; only warns when no downgrade patcher exists for your build
• Fika co-op — Install/update Fika, enable co-op, and set host IP
• Mods (Forge) — Browse/install from The Forge (zip + 7z), manage installed mods (enable/disable/remove), update checks, and dependency hints
• Servers & Tools — Local/remote server helpers and developer utilities
• Self-update — Checks GitHub releases and replaces the installed launcher in place

Note: Forge Tools (standalone utilities) are opened in the browser rather than auto-installed.

Requirements

• Windows 10/11
• .NET 8.0 (included in self-contained releases)
• A legitimate Escape From Tarkov install (for SPT install / updates that need the downgrader)
• An SPT install (or use the in-app installer on first run)

Installation

1. Download the latest release from Releases
2. Extract anywhere you like
3. Run SPTLauncher.exe

Building from Source

Prerequisites

• .NET 8.0 SDK
• Visual Studio 2022 (or another IDE / dotnet CLI)

Build & run

dotnet build
dotnet run

Publish a self-contained exe

dotnet publish -c Release -r win-x64 --self-contained true

Usage

First-time setup

1. Start the launcher
2. If SPT isn’t set up yet, the Get set up wizard appears:
   1. Install SPT (or choose “I already have SPT”)
   2. Auto-detect / Browse for SPT.Launcher.exe
   3. Continue to the main launcher
3. Optionally enable Fika under Show setup

Day-to-day play

1. Open the Launcher tab
2. Check Readiness (SPT / Tarkov / Fika)
3. Click Launch SPT
4. Use Stop to shut down related SPT processes

Tarkov / patcher status

• Live Tarkov is read from your BSG install (registry / exe), not the already-downpatched SPT copy
• If a matching CDN patcher exists for your live version, install/update can proceed
• The “no patcher” warning only appears when no downgrade patcher is found for your live Tarkov → SPT target
• After SPT is already installed, Tarkov shows as a live install — patcher details are hidden unless something is wrong

Updates

• SPT — Update / install actions on the readiness row; advanced recovery under Show setup
• Fika — Install or Update when a newer client/server build is available
• This launcher — Banner prompt when a newer GitHub release is available

Servers

Use the Servers tab for local/remote server configuration and related helpers.

Configuration

Stored under:

• Settings: %APPDATA%\SPT Launcher WPF\settings.json
• Server configs: %APPDATA%\SPT Launcher WPF\servers.json

SPT’s own launcher config (including Fika IP / dev mode) lives next to your SPT install (e.g. under SPT_Runtime / launcher user data).

Troubleshooting

App won’t start

• Use a release build of SPTLauncher.exe, or install the .NET 8 runtime for framework-dependent builds
• Try running as administrator only if Windows blocks the exe

SPT path / auto-detect fails

• Newer SPT builds put the launcher at ...\SPT_Runtime\SPT.Launcher.exe
• Use Auto-detect after install, or Browse to that file
• Desktop / install-folder SPT.Launcher.lnk shortcuts are also resolved

“No patcher for this Tarkov version yet”

• BSG updated live Tarkov and SPT hasn’t published a matching Patcher_{live}_to_{target}.7z yet
• Wait for the patcher, then click Recheck
• Keep live Tarkov updated — the official SPT installer uses the newest matching patcher when available

Launch / Stop issues

• Confirm SPT.Launcher.exe under Show setup
• Check antivirus isn’t blocking SPT or this launcher
• Stop targets SPT-related processes; it won’t close this app

Fika

• Install Fika into your SPT folder when prompted
• Enable Fika co-op and save the host IP under Show setup
