I guess you don't have the mnemonic phrase and thus I'll ask, inside the zip, do you have any file that contains the private keys on a wallet import format? Examples:

If you do, then open your electrum, click "File" -> "New/Restore" -> Name your wallet -> "Import Bitcoin addresses or private keys" -> paste your private keys on that text field and hit "Next".
If you don't, then you may have your wallet backed up on a file without extension. Electrum probably allowed you to name that wallet file and if you open it with notepad it looks like that:

You just open that file with electrum.
You may receive private messages from users that "want to help you". It may be meaningless to mention, but:
- Never reveal any private key(s).
- Never reveal any seed or mnemonic phrase.
- Never give your wallet file to anyone.
- Do not download any "legit" program that will "help" you recover your funds.
