Can I download from the gallery without updating my game?

1. if you have other pc/laptop (not necessary gaming capable) install the sims 4 in there and update it to the latest version, download all gallery items then copy the entire tray files to your primary pc

2. (not sure if this will work though, but most likely it will) - Copy your entire the sims 4 folder somewhere else or to another partition. backup your the sims 4 document folders, update the original the sims 4 folder to latest version, download all gallery items, rename the new the sims 4 folder to anything else. turn off automatic game update from origin, restore your original(old version) of ts4 documents folder and grab the tray files from the new version of ts4 documents, launch your old version of ts4 directly through its .exe file not through origin library.
