|I do not know the registry entries for adobe, but you are missing a path if it cannot find %appdata%|
Have you used a registry cleaner? If so, install the registry backup that you made before this error occurred. Most cleaners prompt you and/or create a backup of the registry before making changes or deletions.
Lastly, if you cannot find a list of registry entries for adobe and/or do not feel comfortable making the changes, you can reinstall the application.
