3. Move the existing Adobe Unit Types.osax file to a backup location.
4. Copy the downloaded version of the Adobe Unit Types.osax file to the /Library/ScriptingAdditions folder. Select Yes to authenticate this operation.

2. Select Open in 32-bit mode.

Solution 3: Us the Arch command in your command line tool.
