wallet.dat can be of a ton of coins. Litecoin also uses wallet.dat. I once found a wallet.dat file lying around some DVD, I thought "great, a lost BTC wallet", but then I was confused because it didn't work. Well it turned out that it was a Litecoin wallet.dat file.
I don't know if there is a way to know of what coin the wallet.dat file is from, that would be handy to know, because right now I can do nothing but randomly try around with all the altcoins that I ever held.
According to his pic wallet.dat is from 19 June 2011 and litecoin was introduced in oct 2011 however it can be "swiftcoin" but I doubt.
OP you should try installing bitcoin first.
