itch.io

Currently unpacking the torrents for the full collection to see if those work, but Oof @ the number of hours.
I've downloaded the standalone Sims 3 file though and it appears to lack a launcher.  The creator's YT link is borked and i don't have twitter/x to reach out to them.  Has anybody managed to get these files to work?
TIA
