Since you are using a very old version of Zcash you should probably start a fresh node on Linux (Zcashd) or Windows (ZecWallet Fullnode) and transfer the old wallet.dat file into the new node.

Instructions to do that here: [Wallet.dat deleted - #6 by daira](https://forum.zcashcommunity.com/t/wallet-dat-deleted/36948/6)
