Just recently my game wouldn't load my sims homes and I had to reinstall the game. During moving everything around in my documents so I wouldn't lose anything, I lost a few downloads. What I'm looking for (and it don't have to be the exact ones I had) are windows that are placed at the bottom of the wall. I have this gorgeous house that uses them but I'm missing them now and can't find any anywhere. I would love to have them in black if at all possible. Thank you for your time in advance.

Do you mean long vertical ones or horizontal ones? There's one on here that has three levels of horizontal window, one of which is at the bottom.

Although this is not the house, I downloaded it yesterday to get the windows on the section of the roof (those windows are what I basically need). But I found out I can't install the house because my Clean Installer did not download correctly from Origin and I really don't feel like moving everything again and maybe lose more of my downloads.

Clean Installer is not from Origin, it's player made. Go to your post and click the underlined auto text, it will take you directly to the CI download.

Would these be any good?

The first one on the page is perfect, thank you.

That's the one I was thinking of. Thanks for getting there sooner than I did.
