Perhaps you can inform the user that they must close chrome browser before
uninstalling. And your uninstall script will actually goto the users "User
Data" directory and delete the extension folder which is just your extension
id.

C:\Users\[user]\AppData\Local\Google\Chrome\User
Data\Default\Extensions\[extension-id]
