General Issues and Bug Reporting (Unreal Engine)
1

Summary

In the Epic-distributed Windows build 5.8.0-55116800+++UE5+Release-5.8-Windows, the bundled file Engine/Binaries/ThirdParty/DbgHelp/dbghelp.dll has:

  • File/product version: 10.0.25291.1000.
  • Size: 2232688 bytes.
  • SHA-256: 26113f7ba29a99ca6dbc2382b358c866a68c5fc216ff5f176f0e974b604893c3.

The installed Epic distribution manifest lists this exact SHA-256. The adjacent dbghelp.tps is also an exact match to that manifest, but declares Windows 10 SDK_10.0.19041.0, LicenseFolder=None, and the EULA URL https://docs.microsoft.com/en-us/legal/windows-sdk/license-terms-ewdk. Its redistribution audiences are Licensees/Git/P4.

Could the component owner please confirm:

  1. The original Microsoft supplier product/package, release/servicing identity and architecture that supplied this exact DLL hash/build. A file build number is not being assumed to equal an SDK package version.
  2. Whether this TPS version/EULA association is current for that binary, and the corrected authoritative metadata if it is not.
  3. The applicable license/redistribution text and exact copyright/third-party notice files or attributions required when the unmodified bundled DLL is included with a packaged commercial Unreal game, including whether any additional Microsoft SDK license acquisition is required.
  4. Whether Epic can supply an original package/file record or documented equivalent that binds those terms/notices to the identified payload.

We are retaining the bundled files unchanged. We are not inferring a production grant from a generic REDIST filename list, a newer SDK, a preview package with a nearby version, or diagnostic-use consent. No engine source, credentials, account data, private logs, game assets or local absolute paths are included in this question. No attachments are proposed.

Please route the licensing/provenance portion to the responsible third-party component owner.

Documentation

Steps to Reproduce

  1. Examine the Epic-distributed Windows build 5.8.0-55116800+++UE5+Release-5.8-Windows.
  2. Read the version resource of Engine/Binaries/ThirdParty/DbgHelp/dbghelp.dll and compare its identity with the installed Epic distribution manifest.
  3. Read the adjacent dbghelp.tps and compare its declared SDK identity and EULA reference.
    These are the already-recorded observations; no Editor launch or crash reproduction is needed for this metadata report.

Expected Result

The supplied component metadata should identify the original Microsoft package corresponding to the bundled DLL build/hash and the applicable complete license, redistribution terms and required notices. Please confirm the four supplier questions in the Summary.

Observed Result

The manifest-matching bundled DLL is build 10.0.25291.1000, 2232688 bytes, SHA-256 26113f7ba29a99ca6dbc2382b358c866a68c5fc216ff5f176f0e974b604893c3. The same Epic distribution supplies the adjacent TPS declaring Windows 10 SDK_10.0.19041.0, LicenseFolder=None and the EWDK license URL. The original supplier-package and complete notice applicability are not established by those fields.
