Steam client prep before your first ESP profile on Windows.

Loader closes instantly on my Windows 11 laptop. I read conflicting posts — some say disable security features, others say enable HVCI. Which is it for this product?

TPM shows enabled in BIOS. Secure Boot is on. Steam Palworld launches fine without the trainer. Intel CPU, Nvidia GPU, build 23H2.

Is Game Pass supported or strictly Steam? I only own the Steam copy.

For this build you want Memory Integrity (HVCI) and Core Isolation enabled, not disabled. Same for TPM and Secure Boot. The loader expects a modern Windows security stack.

Steam client only — other launchers are unsupported per the requirements page.

Disable Discord overlay, GeForce Experience capture and aggressive RGB suites. They hook the game and break inject even when HVCI is correct.

Supported builds are Windows 10 or 11 from 21H2 through 25H2. If inject still fails after security toggles, check antivirus quarantine before blaming Windows.

Enable HVCI, Core Isolation, TPM and Secure Boot. Close overlays. Launch Palworld through Steam, then loader. Game Pass and non-Steam clients are not supported.

See the Windows setup guide for screenshot paths in Windows Security. Thread archived.
