Install D4LF and get your Diablo 4 loot filter setup running cleanly.

Follow the release download, DLL setup, TTS notes, and required game settings in one pass.

Install Summary

Use this short checklist when you want the few setup decisions most likely to block a first successful run.

  • Release package. Start from the latest GitHub release zip so your files and season-specific fixes match the current upstream build.

  • DLL helper. Run install_dll.cmd with the real Diablo IV path so the helper DLL is copied and signed before the game launches.

  • Game settings. Check language, tooltip, font scale, HDR, and both screen-reader options before assuming the loot filter itself is broken.

Install steps

  1. Download the current release. Download the latest .zip from GitHub Releases and extract it.
  2. Copy the Diablo IV path. Copy your Diablo IV install path from Battle.net or Steam.
  3. Run the DLL installer. Run install_dll.cmd, provide the game path, and allow certificate installation.
  4. Enable a profile. Create or import a profile, then enable it from the D4LF config window before your first filter run.
  5. Verify in-game settings. Verify the required in-game settings, restart D4LF if needed, and launch Diablo IV.

TTS setup notes

D4LF reads item information from screen state and accessibility TTS output. The install_dll.cmd script copies the DLL, downloads the required signing tool, and signs the DLL so Diablo IV can load it.

If you prefer terminal usage, you can also run .\install_dll.cmd manually, with the optional -signtool_path override for advanced setups.

Required game settings

  • Game Language must be English.
  • Advanced Tooltip Information must be enabled.
  • Font scale must be set to Small or Medium.
  • HDR must be disabled.
  • Use Screen Reader and 3rd Party Screen Reader must be enabled.

Move into config and profile work if D4LF launches, or confirm the environment limits first if the tool still does not behave as expected.

Profiles and configs

Check the .d4lf folder layout, params.ini, and the profile settings that usually matter first.
