I found that topic earlier and I'm having him try it as we speak.
He tried this and it failed looks like its lost forever. At least he learned to backup his wallet from now on.
Try to run Windows system restore and restore to a previous point OR you might want to restore to the previous Windows version. That wallet might not be corrupted.

Just use private keys
^ Copy that key
Open on new machine
Remove all the < and > obviously
Code:
dumpprivkey
^ Copy that key
Open on new machine
Code:
importprivkey
Remove all the < and > obviously
I don't know what the private key is and I can't determine it from the wallet.dat because it is corrupted.

think the problem is not how to get old wallet to new client
problem is corrupted wallet file
problem is corrupted wallet file
you are correct...it says its corrupted and the wallet just closes
ok...then, follow this directions.
Corrupt wallets used to cause a DB_RUNRECOVERY uncaught exception and a
crash. This commit does three things:
1) Runs a BDB verify early in the startup process, and if there is a
low-level problem with the database:
*Moves the bad wallet.dat to wallet.timestamp.bak
*Runs a 'salvage' operation to get key/value pairs, and writes them to a new wallet.dat
*Continues with startup.
2) Much more tolerant of serialization errors. All errors in deserialization
are tolerated EXCEPT for errors related to reading keypairs
or master key records-- those are reported and then shut down, so the user
can get help (or recover from a backup).
3) Adds a new -salvagewallet option, which:
*Moves the wallet.dat to wallet.timestamp.bak
*extracts ONLY keypairs and master keys into a new wallet.dat
*soft-sets -rescan, to recreate transaction history

Just paste the old wallet file in the folder %APPDATA%\Litecoin\ it should work.
This folder is usually located in C:\Users\..... (user name).... \AppData\Roaming\Litecoin
This folder is usually located in C:\Users\..... (user name).... \AppData\Roaming\Litecoin
Install a new litecoin wallet
let it sync
close wallet
name your old data file wallet.dat
copy and past wallet.dat at appdata folder to replace the existing wallet.dat file
open run litecoin wallet
let it sync
close wallet
name your old data file wallet.dat
copy and past wallet.dat at appdata folder to replace the existing wallet.dat file
open run litecoin wallet
Tried it with no luck.
Try recovering the file with GetDataBack.
Thanks for the reply but I do not understand what you just said.
Rename bitcoin.dat in wallet.dat et put in the dossier bitcoin de appdata normaly it's good.
Long story short my friend reinstalled windows and did not realize that the wallet.dat file was on his c drive. He used recuva to read the old wallet.dat file but when used in litecoin it says it is corrupted. I tried using pywallet with no success. He had around 30 ltc in it and anyone that can help access it will get a 20% bounty. Any help would be greatly appreciated. Thanks.
