I have a really old wallet.dat file that I'm trying to restore, and whenever I put it in the data folder, bitcoin fails to start and gives me this error:

Maybe try using an older version of bitcoin? they should all be backwards compatible, but give it a shot anyways. As a last resort you should be able to extract the priv keys from that file and put them in a newly created wallet.dat

If this doesn't help you can try Gavin's Bitcoin Tools:

to extract the keys.

Do you have any other copies of the wallet file you can compare it with, to ensure your "really old copy" is still bit-for-bit accurate?

Export your private key to the new wallet with PyWallet or dumpprivkey/importprivkey pair API
