Lightroom Sync with Cloud - Error and full

You want Lightroom Classic and not Lightroom Cloudy. Classic is the actual update to Lightroom. Adobe makes this extremely confusing but for almost everybody Lightroom Classic is the right version. Lightroom Cloudy (Adobe calls it just Lightroom which of course confuses everybody) is really a port of the version of Lightroom for mobile platforms to desktop computers and is the right version only if you want to store all your images in the cloud, and never print, social share, make slideshows, etc. etc. For everybody else Classic is the right choice.

If you really wanted to stay with the Lightroom that stores all files locally, luckily it is easy to delete everything from the cloud. First open your old Lightroom version whihc should still be there. This should give you an interface where at the top you can select Library, Develop, Map, Book, etc.). The Cloud version does not have any of these modules. Check if you see every image there and whether you can access them all. If so, log onto https://lightroom.adobe.com. Click on the icon that looks like a nose in a circle at the upper right top and select "account info". Then hit "Delete Lightroom Library". This deletes everything you uploaded to the cloud and should delete everything in the Lightroom Cloud version you installed on your computer. Now go to the creative cloud app and install Lightroom Classic. Open this and you should find all your old images in your previous catalog intact. It should just upgrade the old catalog to the newer version.
