🔒 Local file access restricted (CORS)

Your browser is blocking direct access to local files (file://) due to standard security policies (CORS). To open your documentation, please choose one of the options below:

🟢 Option 1: Select files manually (recommended & safe)

Simply select your data pack and help file below. No installation or settings changes required.

🌐 Option 2: Use our online PWA

Avoid file dialogs entirely by using our live web app. Upload your public GitHub repository, pass URI and read your documentation instantly at https://helpviewer.github.io.

🛠️ Option 3: For Developers (local server)

To load files automatically via URL parameters (?d=file.zip), run HelpViewer through a local web server (e.g., using our lightweight HTTP server for Linux musl libc (main) or Windows (main.exe) or Podman/Docker image) on localhost.

🔴 Option 4: Bypass CORS policy (not recommended, can lead to security risk)

Alternatively you need to run your browser in mode with bypass CORS policy:

• Chrome:

  Run in CLI: chrome.exe --disable-site-isolation-trials --disable-web-security --user-data-dir="C:\temp"

• Edge:

  Run in CLI: msedge --disable-web-security --user-data-dir="C:\temp"
