141  Bitcoin / Bitcoin Technical Support / Re: Bitcoin core uninstall problem on: September 06, 2017, 05:51:26 PM
How do I uninstall Bitcoin core when it won't show up in programs. I can still get to it via %APPDATA% but I want to completely uninstall it. I had a Bitcoin core on my pc but the uninstall exe didn't work so I reinstalled hoping it would fix what was there already. I then used the uninstall exe and all it did was remove the newer one, but the old is still there. Can I just go to the folder in APPDATA and right click and delete all the individual components? will that remove it all?. Thanks.

You can go ahead and do that, however, first try this (as I assume your OS is Windows):
Start>control panel>programs and features.
Then scroll down the list to where bitcoin core/bitcoin-qt is listed, right click and click "uninstall or change a program". And then try uninstalling it that way.
The trouble is that the bitcoin core remaining doesn't show itself in programs.

Hi, i can get to the right place by %APPDATA% and find user/roaming/Bitcoin easily, that isn't the problem. What i don't understand is why the wallet file is named wallet and not wallet.dat in a new download of core. If i delete it and replace with my wallet.dat then it just runs core as normal without using the file i have inserted. After i shut down core and have another look at folders, i find my wallet.dat plus a file just named wallet again?.
You might want to check that Explorer is set to show file extensions properly. It is possible that your "wallet.dat" is actually wallet.dat.dat and that the newly created "wallet" is actually wallet.dat and Windows is "helpfully" hiding the ".dat" extension Undecided

You can check this setting on Windows 10 fairly easily:

Thanks, I think you have sussed it, but I don't know why the setting changed as it was working as it should a few days ago. I will carry on testing my wallets later after work thanks again.

How do i clear previous debug info to make it clearer.?
146  Bitcoin / Bitcoin Technical Support / Re: Testing old wallet.dats on: September 05, 2017, 07:43:26 PM
Why does core create a new wallet file every time i insert a new wallet.dat and i end up with one named wallet and the one i inserted named wallet.dat.?
It can get confusing. Each time the core software runs it checks for a wallet.dat file. If one is not present it will make a new wallet and run that one. I rename all the wallets I work with then change the name back to wallet.dat when I put it in the bitcoin folder. Otherwise I risk overwriting a full wallet with an empty one.

if you use Winxx you should be able to find your hidden bitcoin folder by running
Code:
%appdata%
in the run box. If you are using Linux (which you should) you can find the .bitcoin folder by showing hidden files in your home folder.

Hope this helps.
Thanks for the reply. Why is it not attempting to use the wallet.dat file that i have inserted, at the very least it could say wallet corrupted.

Hmmm. It should. Are you sure it is the correct folder? It will be the one that core created the wallet.dat folder in. You will have to excuse my ignorance of windows, if that is what you are using. But I sort of recall that windows hides the folder with the wallet but displays another "bitcoin" folder.
Also make sure that the name is "wallet.dat". Anything else will be ignored. If it's corrupted I would expect an error, but maybe not?
Did that help?
Definitely the correct folder.

Get the folder path you think is the right folder and run cmd (if it is Windows) and then type path+bitcoin-qt -datadir=appDataFolder

Replacing " path" with where bitcoin-qt is and appDataFolder with the "...appData\bitcoin".


Alternative method:
Boot bitcoin-qt and click help>debug and the datadir should be listed there, copy the wallet.dat file in there.

Hi, i can get to the right place by %APPDATA% and find user/roaming/Bitcoin easily, that isn't the problem. What i don't understand is why the wallet file is named wallet and not wallet.dat in a new download of core. If i delete it and replace with my wallet.dat then it just runs core as normal without using the file i have inserted. After i shut down core and have another look at folders, i find my wallet.dat plus a file just named wallet again?.

Definitely the correct folder. Should the wallet in Bitcoin core be named wallet or wallet.dat,  as in this  fresh download of core it is just called wallet?.

The uninstall shortcut says it has been changed or moved. Bitcoin core doesn't show up in programs list either so i can't uninstall from there. I'm running Windows 10.

151  Bitcoin / Bitcoin Technical Support / Re: Testing old wallet.dats on: September 05, 2017, 12:52:04 PM
No, you only need to sync it to see the transactions. If you load it up and use "dumpwallet" you should be able to get all the addresses and keys straight away.

"salvagewallet" is a last ditch attempt to extract keys from a wallet... it is not recommended unless you have exhausted all other options of wallet recovery... as it can mess up a perfectly fine wallet.

So they won't show via file-addresses straightaway?, before sync?. Thanks.
152  Bitcoin / Bitcoin Technical Support / Re: Testing old wallet.dats on: September 05, 2017, 11:43:41 AM
Does it need to sync past 2013 to have the addresses?.
153  Bitcoin / Bitcoin Technical Support / Testing old wallet.dats on: September 05, 2017, 10:30:07 AM
I have 5 old wallet files from the middle of 2013 for bitcoin core. What is the best procedure for trying them out in the latest bitcoin core?.
Should I run salvagewallet straight away or not?, and do I have to let it sync before I can tell whether there are Btc in the wallet via addresses?. Also what is the original command if I want to run it in standard command after removing the salvagewallet command (i forgot what the original was!).  Thanks again for any help.

How did you install this for windows 10 if you don't mind me asking?, Thanks. I really really need to run it on a corrupt wallet.dat that I have.

I followed this post here: https://bitcointalk.org/index.php?topic=1288078.msg13238007#msg13238007

For the command line stuff I ran PowerShell as administrator and used Set-Location <path to folder> instead of the Shift-Right Click stuff.

For example: Set-Location C:\Python27\Scripts

Hope this helps!

Thanks for the reply but I need someone to do a detailed run through for Windows 10 for a computer novice. Thanks again.

Hi, I just found an old wallet from August 2011. I've tried using this tool to recover it and it creates the following files:

_db.001 24k
_db.002 64k
_db.003 264k
_db.004 96k
_db.005 512k
_db.006 48k
wallet.txt 0k

I couldn't find any information as to why it comes out as empty nor did I find any fix to this problem. I also tried using Bitcoin Core to recover it but it didn't work, and also tried bitcoin-qt 0.7.0 but it didn't work either. These are both newer than my wallet but I couldn't find any older clients anywhere.

Does this mean it's completely corrupt? Thankful for any help trying to recover this as I haven't found anyone else with this particular problem.
How did you install this for windows 10 if you don't mind me asking?, Thanks. I really really need to run it on a corrupt wallet.dat that I have.

How can I tell if the wallet was locked the last time it was used?.
If your wallet has a password on it, then it is always locked. There is never a time where the wallet is unlocked on disk.

Got you, that's why when you unlock it is for a finite time.
157  Bitcoin / Bitcoin Technical Support / Re: private keys in hexadecimal help on: August 31, 2017, 05:10:45 PM
Have you tried using Bitcoin Core's -salvagewallet option yet? Although -salvagewallet has a few issues, it should help if your wallet is corrupted. But before you do that, always make sure that you have a backup of your wallet somewhere.

Already tried that, it said wallet.dat corrupt salvage failed. How can I tell if the wallet was locked the last time it was used?.
158  Bitcoin / Bitcoin Technical Support / Re: private keys in hexadecimal help on: August 31, 2017, 06:22:40 AM
How old is the wallet.dat? Was it from a recent version of Bitcoin Core or an older version? If it is from a new version... you may find that pywallet doesn't handle it very well... it would appear that the devs added a number of new data fields into wallet.dat and pywallet will likely complain loudly about unknown records.

It's from about 2013.
159  Bitcoin / Bitcoin Technical Support / Re: private keys in hexadecimal help on: August 30, 2017, 05:10:01 PM
The wallet is corrupted and I don't know how to get pywallet up and running unfortunately. I know it's a long shot and not being very computer savvy doesn't help, but I am not ready to give up yet when this amount is at stake. Cheers.

Try using the -salvagewallet command (look at the help screen for the implementation of this on the newest version of core). You may also have to use -updatewallet.

If not, if you can tell me the operating system you're using, I'll try to see if I can build a script that will install pywallet for you (with the dependencies) and then you just have to look at how to run commands from that.

You could also look at contacting the user jackjack who is the developer of pywallet, he might be able to try to get your private keys for you.
Hi, that would be great if you could do that i'm running Windows 10. I asked jackjack if he was going to release an updated version with a gui like he said that he was going to but didn't hear anything from him. I guess he is very busy  which is fair enough, and I think he figures that nobody needs pywallet anymore, but I certainly do and probably others too.
160  Bitcoin / Bitcoin Technical Support / Re: Found a bitcoin wallet on my old computer, what can I do? on: August 29, 2017, 05:37:40 PM
Can't you just look at the receiving addresses before it syncs and tell if there are some BTC?.
