- Automatic recovery through the standard installer.
- Keep all six editions, the installer launcher and interface, each updater/uninstaller and the MCAD ribbon setup helper at v1.6.1.45.
- Use the ordinary installer for recovery, including repeated reinstalls of the same build.
- Validate downloaded product and build details before replacing installed software; reject packages older than the installer and mismatched MCAD setup helpers.
- Require all six matching packages and automatic reinstall, startup and rollback checks before producing the installer.
- Preserve customer licence, profile and project files during software replacement.
- MCAD installation: Include Resources/default-mcad-mapping.json so the standard installer accepts the complete MCAD package instead of reporting ECHIDNA for a missing required file.
- MCAD package validation: Check all required files, reject missing/empty files and invalid mapping profiles, and load the shipped mapping with the actual MCAD engine before releasing the installer.
- Drawing Extents: Prevent empty or malformed coordinate values from causing an unhandled conversion error; exclude incomplete sources from the coordinate chooser across all editions.
- Drawing Extents replacement: Validate before changes and replace existing extent rectangles in one transaction; retain all existing rectangles when redraw is cancelled or input is rejected.
- Drawing Extents storage: Use consistent decimal-point coordinates across Windows language settings and reject non-finite values in automatic and manual entry.
- DCAD/MCAD startup: Remove known obsolete bundled .NET files left by earlier installations when applying the framework-dependent package.
infrADAC MCAD v1.6.1.45 - Hotfix Release
infrADAC ACAD / Installer / v1.6.1.45
infrADAC MCAD
Matching MCAD release at v1.6.1.45. Combined maintenance release for ACAD, ACAD LT, BCAD, BCAD Lite, DCAD and MCAD, with the matching v1.6.1.45 installer, updater and uninstaller. Corrects the MCAD package being rejected by the installer with support code ECHIDNA because Resources/default-mcad-mapping.json was absent. The mapping file is now included at the required path. Package release checks run the actual installer validation against all six edition ZIPs. Users recovering a missing DCAD toolbar or MCAD ribbon should close their CAD application, run the matching v1.6.1.45 installer again for their edition, then reopen the CAD application. The normal installer performs the recovery automatically and retains existing licences, profiles and customer project files. Reinstallation removes obsolete bundled .NET files that can prevent DCAD and MCAD from starting, then reinstalls the host integration. DCAD retains the dedicated ADAC Panel icon and uses the installed .NET 8 Desktop Runtime x64 without bundling the runtime. Fixes Set Drawing Extents failing when a stored or object coordinate is blank, incomplete or invalid. Only complete coordinate sources are offered. Coordinates are validated before changing the drawing, and cancelling a redraw preserves existing extents. All previous fixes remain, including saved Global Attributes and preset storage/recovery, complete XML attribute ordering, BCAD rising main linetype fallback and DCAD startup/session handling.
