If you have changed the name of your Claris Emailer Folder, the Claris Emailer 1.1v2 updater will update your application file to Claris Emailer 1.1v2 and will create a new Claris Emailer Folder inside of your existing folder with all of the new Claris Emailer Files and support files in it.
To resolve this issue, rename your folder than holds Claris Emailer 1.x to Claris Emailer Folder and rerun the updater to update all of the files. You can then delete the duplicate Claris Emailer Folder.
