Hi Antonia,
Version 2.0.9 has a lot changes with version 2.0.8, so we can't update manually. The only way to update OS Property from 2.0.8 to 2.0.9 is install the latest version 2.0.9. Of course, when you install 2.0.9, you won't lose the existing data or configuration.
Please remember to install the modules also. Because in 2.0.9, we have new important point, OS Property will save the pictures of properties in separated directories instead of one general folder as old versions.
Thanks
Dam
