Importing File Types

I got a poblem with Opus 8.

I want import the file types of a computer to another. I've changed icons, shell extension etc... on this computer and i don't want to do it again on the other one. Problem is wahen i export the settings (only the file types) and import them on the target machine, nothing changes...

Someone has an idee ?

Make sure you have administrator privileges on the new computer when you do the import - file types are kept in the registry under HKEY_CLASSES_ROOT and user-level accounts usually don't have write access to that key.
