They will not appear in your those folders. For some reason, this will not happen to those uninstallable files. When a Sim/House/Household is installed through the launcher, a file will be saved to the SavedSims folder (or the library folder in your user data directory.
I don’t know why some Sims show this behavior but it’s possible that CC has something to do with it. They will show as installed but next time you open the launcher, they are uninstalled again. There are many Sims out there that cannot be installed through the launcher.
I’ve downloaded a Sim/House/Household from the exchange but I can’t find it in CAS or in the library Cause
