1. Overview of the Error

When launching Shadow of the Tomb Raider (SOTTR) on PC, some users encounter:

"Failed to initialize Steam. Are you running Steam?"

This occurs even when Steam is clearly running. The error stems from broken communication between the game and the Steam client.

Fix 3: Verify Game Files (Most Common Fix)

  1. Steam → Library → Right-click Shadow of the Tomb Raider → Properties.
  2. Installed Files → Verify integrity of game files.
  3. Wait for completion (Steam will reacquire missing/corrupt files).
  4. Restart Steam and launch the game.

Fix 8: Reinstall Visual C++ Redistributables

  1. Go to SOTTR install folder/_CommonRedist/vcredist/
  2. Run both vc_redist.x64.exe and vc_redist.x86.exe → Repair.
  3. Restart PC.

Overlay and third-party software conflicts

  1. Disable Steam Overlay for the game: right-click game → Properties → uncheck “Enable the Steam Overlay while in-game.”
  2. Disable other overlays (Discord, NVIDIA GeForce Experience, RivaTuner, ReShade).
  3. Close background recording/monitoring tools (MSI Afterburner, OBS, etc.).

  1. Enter Offline Mode in Steam (Steam > Go Offline).
  2. Launch Shadow of the Tomb Raider directly from its installation folder as an administrator.
  3. If the game launches, you know the problem is strictly the live API handshake. This points to a firewall or network issue. Disable IPv6 on your network adapter or reset your Windows Hosts file (C:\Windows\System32\drivers\etc\hosts).

Note: For some voices (Bane and Dalek, for example), you'll need to put on the correct "accent" for the voice transformation to work properly. Basically, try to make your voice sound like the target voice, and the engine will add some effects to make it sound like the real thing. Another random tip: You'll need to talk relatively slowly if you're using any of the "echo-ey" voices, otherwise the echos will make it hard to understand.
