I need to download SQL Server 2016 LocalDB for a separate project. Before I do that I want to ensure that this will not affect the Organizer in Photoshop Elements 15. I have a very large number of photos in that database and I do not want to do anything that will threaten the catalog. My operating system is Windows 10. Does anyone know whether I am okay doing this?
Wouldn't you have to load the Elements DB file into the software for it to have an effect? And I believe Elements uses a SQLite database if that makes any difference.
If you're concerened about damaging your catalog, why don't you back it up. If you just copy the catalog folder, using Windows File Explorer, it is not very large. You should of course also backup your image files: the Organizer's Backup utility is specifically made for that purpose.
