Back with a question re: Sims 3 Pets

Got Sims 3 downloaded okay, and now I'm on Pets. I followed the Installation Guide and now the setup is saying "Please insert disk that contains the file Support/Readme/en/en_EULA.rtf.
Looked in the guide and it isn't saying anything about this?

Hello there,

Welcome back!
This should do: https://games4theworld.forumotion.com/t2251-the-sims-3-pets-please-insert-disk-1-official-fix

Thanks! I guess I downloaded the wrong pets. The download page is down so it was a little harder to find the right one on the other site. Again, thank you very much!

Hello,

You're welcome!
Anything else we can currently help you with?

I may need more help later, if you could keep this open please. I think I need to step back from trying to install for a bit. I confused myself again, and as a mother of 2 under the age of 3.. It takes a bit to get things done.

Hello,

No problem at all, we'll keep this topic open for you, please let us know the final result!

Got them all downloaded. Working on the fix and update now. For some reason manual patch wouldn't even open for me, so I restarted my computer. Redownloading it and will update on if it opens this time

//EDIT

No luck. It won't open once it's done downloading. It momentarily freezes my browser then does nothing.

Edit: I think I got it. My game was already up to date. Will try to play and then update this!

What version of the game are you updating to?

Each Expansion has a manual patch in it for the game to update itself when installing.

Under support/updates I think.

It's working One question left. I selected a pet (I got pets as well) and went to select my person after and the pet/person showing when you select was stuck on the dog even though I had selected the person. Any known fix to this?

I did, but haven't restarted the game since. I know I've had this issue before. Wasn't sure if there was an easy fix to it.
