Found an old hard drive at my parents with a wallet on it from 2016, how do i go about recovering it?

Went to my parents and found a PC sitting outside, recovered the harddrive and while browsing found out that there is a MultiBitHD wallet on it from 2016.

Im able to go and find the actual "mbhd.wallet.aes" files, along with what looks like some backup files, but I have no idea what I would do to even begin recovering this wallet. Some cursory googling says there are tools out there for unencrypting these wallets (hashchat) but, again, ive never attempted using anything like that before so if theres any information that could point me in the right direction that would be great.

I also know that the passphrase for the wallet is long gone, but the computer belonged to my brother, so if I need to "try out" passwords, I can likely ask him

**edit: my brother knows I have this hard drive, and doesnt know if there is anything still on the wallet
