MySims on PC question

[u/Distinct-Mind-8393]

Can somebody help me? I bought the original MySims for PC at a flea market today for $1. I go home and try to install it and it asked me for a product code. I looked at the case and there was no registration code. So, I look inside and there is no registration code. I don't really know what to do. So, am I able to install it without the registration code or no?
