If the walet.aes.json file still the original file that has bitcoin and you have the password for this wallet then you can able to access the wallet.
The wallet password that you use before should be the same. About the seed, I think you don't need the seed if you already have this wallet file and password.
You can open this wallet using this link
https://login.blockchain.com/wallet/import-wallet and then use the password that you used before.
Take note don't trust any newbie like the post above mostly they are scammer. Oppsss. the post is gone.
