The ROES Client may fail to install/launch on occasion. While rare in OS X, it can occur because of a bad connection to our distribution servers on the Internet or a permissions issue locally. In case of an error dialog that lists an initialization error or a class not found, it is best to go clean out the attempted install and start fresh.
To do this, open Finder and in the top menu click Go and select Go to folder from the list. A dialog window will open with a field to type a path into. Please enter:
~/.ROESEngineCache
and click OK/Open. When the new Finder window opens select the entire contents of the folder and send to Trash.
Open the launch.dmg again and re-execute the LOKTAHROES.app file listed when the file unpacks. It should then install and start correctly. If there is still a failure, copy the .app file into your Applications folder and try to execute it from there.
