Hey everyone. I've been struggling for years to get my wallet.dat file back. I think there’s around 0.02 btc or something like that in it. I tried installing the latest bitcoin core 25, but it keeps saying that the wallet file is from a different chain. Now I'm trying to set up bitcoin core 0.8 on my Linux PC, but I’m running into library problems like "./bitcoin-qt: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory". What other options do I have? What should I do? Thanks for any help!!!

Do you have access to a Windows machine? You can get the older binaries and run those to get access to the wallet. https://bitcoincore.org/bin/insecure/ Start at .0.8.6 and work your way up to the newer versions. At some point it will probably prompt you to update your wallet. Never work with your original wallet, always use a backup copy.

Either your wallet is incorrect, or your wallet is indeed for a different chain. The error is unlikely to be wrong. Tons of altcoins begin by forking Bitcoin Core. They will all have wallets named wallet.dat. It's possible that your wallet is for such an altcoin.

Does the Core Client perhaps need the blockchain? Or does it open the old wallet without it?

It's not useful to open the wallet without having access to the blockchain and the network. Without those, transactions cannot be received or sent.

With or without the blockchain, it'll show that error if the wallet.dat is from another chain or Altcoin. He can force to load it by starting 'Bitcoin Core' with --walletcrosschain arg or by setting walletcrosschain=1 in his bitcoin.conf file; But without the blockchain, he won't be able to scan for transactions related to his wallet.
