- Download the appropriate installer (Windows
.exeor macOS.dmg).
5) Troubleshooting common issues
- Installer won’t run: Verify OS compatibility and install missing runtimes (e.g., Visual C++ redistributables).
- Activation fails: Check license status with Graphisoft or your reseller. Offline activations may be necessary for deprecated online services.
- Crashes or graphics glitches: Update GPU drivers; if on macOS, older OpenGL-based rendering may be limited on recent macOS versions.
- File compatibility with newer Archicad versions: Use IFC exports or consult Graphisoft’s versioning guidance to migrate projects.
