Re: Why can I not find the newest patch
@flaoties Patch 1.70 is the designation for the 64-bit Mac version of Sims 3. You can't install it in Windows and don't need to have it in order to download store content.
Instead, go into Documents > Electronic Arts > The Sims 3 > Downloads and delete any copies of Monte Vista you see there. Then download a fresh copy and try to install it. Let me know whether it works.
