If I install R&L and not touch the world or its people, will it corrupt my save?

Hello Mac Users of the Sims! I'm one of the lucky folks who's save file got absolutely murdered by trying to edit the R&L world and it's townies. Thankfully, I have back-ups and didn't lose too much data. If I were to install the pack, but not touch anything other than the pack content (CAS, Build/Buy), will it corrupt my file again?

Thank you in advance!
