Install for a single user

  1. Extract the downloaded ZIP file.
  2. Copy all contents from .\archicad{VERSION}\Speckle.apx to %AppData%\Speckle\Archicad\v3\{VERSION}\Add-Ons\
    • Replace {VERSION} with your Archicad version (example: 27)
    • Create the directory if it doesn’t exist
  3. Open Registry Editor and navigate to HKEY_CURRENT_USER\Software\GRAPHISOFT\Archicad\{VERSION}\Add-On Manager\Include
  4. Increment the key value by 1
    • If the key doesn’t exist, set the value to 1
  5. Create a new string value with that number prefixed by # (example: #1)
    • Set the value type to REG_SZ
    • Set the value to lan.flat:///%APPDATA%/Speckle/Archicad/v3/{VERSION}/Add-Ons/Speckle.apx
    • Replace {VERSION} with your Archicad version
  6. Ensure the following values exist in HKEY_CURRENT_USER\Software\GRAPHISOFT\Archicad\{VERSION}\Add-On Manager:
    • Default Location (REG_SZ): %DEFAULT%
    • Use Default Location (REG_DWORD): 1
    • Create these values if they don’t exist
The default location values ensure the connector appears properly in Archicad’s Add-On Manager.

Verify installation

Open Archicad and check the Add-On Manager to confirm that the Speckle connector appears in the list of add-ons.

Uninstall the connector

  1. Delete the Speckle.apx file from %AppData%\Speckle\Archicad\v3\{VERSION}\Add-Ons\
  2. Open Registry Editor and navigate to HKEY_CURRENT_USER\Software\GRAPHISOFT\Archicad\{VERSION}\Add-On Manager\Include
  3. Remove the string value you created during installation (example: #1)
  4. Decrement the key value by 1
You don’t need to remove the Default Location and Use Default Location registry keys.
