i can't delete sims 4 legacy edition

Hi,

Recently I accidently 'purchased' the free legacy edition sims 4 on origin, even though I already have the original game and have had it for a long time. This was a mistake because I didn't even know what it was, and thought it was some new free content. I did not download the legacy edition thinking I could just leave it in my origin. However, then I tried to run my game and it wouldn't let me until I downloaded the legacy edition.

I have seen other people suggesting going onto the advanced menu and clicking a drop down menu about game launch options, but I don't have that. (see image attached)

there seems no way for me to delete the sims 4 legacy. I really need assistance.

My computer is a 64-bit, with windows 10. So the legacy edition when I play it also doesn't really work and comes up with a pop up about how I'm running 32-bit on a 64-bit and how it wont run smoothly.

I really hope someone has had the same problem and fixed it. Ill take any suggestion at this point.

Thanks,

Bella
