Softany Txt2Htm2Chm: Complete Guide to Converting TXT to CHM

Troubleshooting Softany Txt2Htm2Chm: Common Issues and Fixes

Softany Txt2Htm2Chm is a convenient tool for converting plain text into HTML and compiling CHM help files. If you run into problems, this guide walks through common issues and practical fixes so you can get back to producing help documentation quickly.

1. Installation fails or program won’t start

• Symptom: Installer aborts, or executable doesn’t launch.
• Likely causes: Missing Visual C++ runtime, blocked by antivirus, corrupted installer.
• Fixes:
  1. Install required runtimes: Ensure Microsoft Visual C++ Redistributable packages (2015–2019) are installed. Download from Microsoft if needed.
  2. Run as Administrator: Right-click installer or exe → Run as administrator.
  3. Temporarily disable antivirus: Pause real-time protection during install; re-enable afterward.
  4. Re-download installer: Get a fresh copy from the official Softany site to avoid corruption.

2. Conversion produces malformed HTML

• Symptom: Output HTML has broken tags, incorrect encoding, or unexpected layout.
• Likely causes: Source TXT uses unusual encoding or contains control characters; wrong conversion settings.
• Fixes:
  1. Set correct input encoding: Open the TXT in a robust editor (Notepad++, VS Code) and confirm encoding (UTF-8, ANSI). Convert to UTF-8 if characters are garbled.
  2. Strip non-printable characters: Use an editor or a command-line tool to remove control characters (e.g., search/replacevs ).
  3. Adjust conversion options: Check any settings for HTML templates, line-wrap, or tag generation in Txt2Htm2Chm and test variations.
  4. Validate HTML: Run the output through an HTML validator to locate structural errors and fix source text accordingly.

3. CHM compilation fails or yields blank help file

• Symptom: The CHM compiler errors out, or the produced CHM shows a blank page or missing content.
• Likely causes: Missing HTML files, incorrect project (.hhp/.hhc/.hhk) settings, or blocked help viewer due to security.
• Fixes:
  1. Check project files: Ensure the HHP, HHC, and HHK files reference the correct HTML filenames and paths.
  2. Verify HTML output exists: Confirm the conversion step created the HTML files in the expected folder.
  3. Use local paths: Use relative paths in project files to avoid absolute-path issues across systems.
  4. ** unblock CHM file after transfer:** If CHM was downloaded, right-click → Properties → Unblock before opening.
  5. Run compiler separately: Try compiling with Microsoft’s HTML Help Workshop directly to see clearer error messages.

4. Images or resources are missing in CHM

• Symptom: Images don’t display or links to CSS/JS fail inside the compiled CHM.
• Likely causes: Resource files not included, incorrect relative paths, or external links blocked.
• Fixes:
  1. Place resources in project folder: Keep images, CSS, and JS in the same folder structure that HHP/HHC expect.
  2. Use relative links: Ensure and stylesheet links use relative paths (e.g., ./images/pic.png).
  3. Include the files in the HHP: Add missing resources explicitly to the HHP file so the compiler includes them.
  4. Avoid absolute/HTTP links: CHM may block external HTTP resources; embed or include them locally.

5. Search in CHM returns no results

• Symptom: Search pane shows no hits even though content exists.
• Likely causes: Indexing disabled, missing keywords, or incorrect compilation options for full-text search.
• Fixes:
  1. Enable index/search in project: Confirm index and full-text search options are enabled in the HHP settings.
  2. Rebuild the CHM index: Recompile the help file after enabling indexing to generate proper search data.
  3. Add keyword entries: Use HHK (index) entries for important topics to improve discoverability.

6. Character encoding issues in CHM (non-Latin scripts)

• Symptom: Chinese/Japanese/Korean or other scripts appear as gibberish.
• Likely causes: CHM format uses legacy codepages; incorrect encoding during HTML generation.
• Fixes:
  1. Use Unicode-aware conversion: Generate HTML with UTF-8 encoding and include .
  2. Set language/codepage in HHP: In the HHP project file, set the appropriate language and codepage entries if supported.
  3. Consider compiling per-language: If CHM viewer doesn’t support UTF-8 properly, use a codepage-compatible encoding or create language-specific CHMs.

7. Unexpected formatting or missing styles

• Symptom: Headings, lists, or tables don’t render as expected in HTML/CHM.
• Likely causes: CSS not applied, inline styles stripped, or conversion templates differ from expectations.
• Fixes:
  1. Include a stylesheet: Reference a consistent CSS file and ensure it’s included in the project.
  2. Check conversion templates: Modify Txt2Htm2Chm templates to produce the desired HTML structure.
  3. Use simple markup in TXT: Keep source formatting simple (clear headings, blank lines) to reduce conversion ambiguity.

8. Permission or access errors when saving output

• Symptom: Errors writing files to disk or saving project changes.
• Likely causes: Folder permissions, UAC, or network drive restrictions.
• Fixes:
  1. Save to local user folder: Use Documents or Desktop rather than Program Files or restricted system folders.
  2. Run program as Administrator when writing to protected locations.
  3. Avoid network paths during compile: Copy project to a local drive, compile, then move output to network share.

9. Slow conversion or high CPU usage

• Symptom: Conversion takes long or consumes large CPU/RAM.
• Likely causes: Very large source files, many embedded resources, or system constraints.
• Fixes:
  1. Split large input files: Break very large TXT into smaller sections and compile separately.
  2. Disable unnecessary options: Turn off features you don’t need (extra logging, preview).
  3. Run on a machine with adequate resources: Use a system with more RAM/CPU for big projects.

10. Error messages with unclear codes

• Symptom: Generic or opaque error codes appear.
• Likely causes: Internal app errors or missing components.
• Fixes:
  1. Check logs: Look for any application logs in the program folder for more detail.
  2. Search the exact error text online: Include quotes around the message to find specific fixes or forum posts.
  3. Update to latest version: Bugs may be fixed in newer releases—download official updates.
  4. Contact support: If nothing helps, provide the error text, OS version, and steps to reproduce when asking Softany or community forums.
