Application Manager for Elements 2018

Linus, if you install a newer version of Elements, it will almost certainly find your existing catalog and will convert it to the newer version automatically.  This will preserve all of your tags etc.   If the newer version doesn't find your 2018 catalog, you can convert it manually, using the File>Manage Catalogs>Convert dialog.  I doubt whether this will be necessary.

Hello,

Please accept our sincere apologies for the inconvenience you had to face. Were you able to resolve the issue by uninstalling and reinstalling the application? If the issue still persists, please try following the steps mentioned in this thread.

Feel free to reach out to me if you have any further queries.

Thanks,

Medha

Sorry, Linus, but this problem has been a major frustration for Elements users because of the changes that have been made to the Adobe Application Manager over the past few years.  The Adobe website is totally useless in finding a solution to this problem.  I would like to suggest that you uninstall and reinstall the program.  If that does not solve the problem, I will try to escalate the issue to somebody on Adobe staff who can help - unless somebody else pops into this thread with a better idea. 

Is the program itself working?  The Application Manager deals with program updates. So, if your program was already up to date, you can ignore the message.  If this is not the case, please give us a screenshot of the error message you are receiving.
