Issue with Using my Original Sims 3 CD's on my current Origin Account

Hi,

I have some The Sims 2 and The Sims 3 discs at home that I used to play with when I was a child. Today, as an adult, I would like to relive both games on my current PCs, but I no longer have access to the Origin account my parents used (which I used to play back then). Therefore, I would like to ask if there is any way to use the original discs I own for The Sims 3 (The Sims 3, Late Night expansion, Into the Future expansion, and a stuff pack) without any issues from my own current account, if I need to prove that those CDs are mine, or how I should proceed (now that I’m an adult). Due to the years that have passed since 2012–2013, I no longer have receipts or anything that could prove my family bought the game for me, but I still have my original CDs.

I am aware that for The Sims 2 the process is much simpler and I only need to adjust compatibility settings. What concerns me is The Sims 3, because I do remember it required Origin.

Thank you very much in advance!
