Version 2026.1

Latest
  • New Native parsing of the /LCID <num> command-line switch in both installer and uninstaller for multi-language projects — no longer requires the language-from-command-line.xml custom action template
  • New Native parsing of the /s and /silent command-line switches in both installer and uninstaller with exact token matching (no sub-string false positives), enabled by default and toggleable from the Progress Monitor settings
  • New Pre-compile validation for component references in shortcuts and registry entries — missing or misspelled component names are reported immediately with a complete list of bad references instead of after several minutes of code generation
  • New New "Don't Show Again" button in the Additional Packages startup dialog so optional addons stop reappearing every session until a newer version is released
  • Improved Enriched runtime crash diagnostics: error messages now include the exception code, resolved fault address, and a stack trace of the calling frames

  • Fixed Fixed a critical regression in 2026.0 causing random Access Violation crashes at runtime in 64-bit installers (typically right after extraction, when writing uninstall entries or component registry values) — root cause was format-string injection
