HexCmp 2, developed by Fairdell Software, is a specialized utility that integrates a visual binary file comparator with a full-featured hexadecimal editor. It is widely used for debugging, reverse engineering, and modifying ECU BIN files in automotive tuning. Registration and Licensing Prefix-based segmentation – HC2 denotes the product

HexCmp 2 is technically distributed as shareware with a trial period. To unlock the full version and remove trial limitations, a registration key is required.

Potential Encoding Patterns:

1. Prefix-based segmentation – HC2 denotes the product.
2. Checksum validation – The last group (2C6F) might be a checksum of the previous groups.
3. Embedded metadata – The key could encode username, company, or expiration date (perpetual vs. subscription).

Some versions of HexCmp 2 use RSA-style signature verification to prevent key generators. If the algorithm is symmetric (e.g., AES or custom rolling XOR), then a reverse engineer could theoretically produce a valid key. If asymmetric, only the publisher can issue keys.

6. Troubleshooting Registration Issues

• Invalid key message:
  • Verify you copied the entire key (no leading/trailing spaces).
  • Confirm key is for HexCmp 2 (not another product/version).
  • Check purchase confirmation for the correct key.
• Key rejected after reinstall:
  • Some keys are limited to N activations; contact vendor support to reset activations.
• License file not accepted:
  • Ensure file extension and contents were not altered or corrupted.
  • Put the license file in the application folder if vendor docs request that.
• Activation server errors:
  • Check firewall/antivirus blocks; allow HexCmp or outbound HTTPS to vendor servers.
  • If behind a proxy or offline, use vendor’s offline activation method.
• “Registered to” shows wrong name:
  • Re-enter registration info exactly as in purchase or contact vendor to reissue.
• Persistent problems:
  • Gather these details before contacting support: product version, OS version, exact error text/screenshots, license key or order number, machine ID (if applicable).
