There are several different types of Bitcoin clients. Server-assisted clients like blockchain.info rely on centralized servers to do their network verification for them. Although the server can't steal the client's bitcoins directly, it can easily execute double-spending-style attacks against the client.

Hello guys,

I am having a major fatal error problem with 0.8.6 and was wondering if anyone could shed some light on what my issues are.

Windows DEP should not be invoked by Bitcoin, it only writes data to the user data directories by default. Have you changed the command-line or bitcoin.conf file to use a datadir option saving data in a different location?

Bitcoin is also not running from the default install location. You should remove the program from the desktop folder, and download the official installer and install it with standard options. Windows may have policies set that prevent a non-installed program from running correctly.

Hi Deepceleron,

I installed this direct from the bitcoin.org website. I have not touched any files. I simply downloaded this to my desktop and ran bitcoin qt.

The only thing I can think of is that I originally ran the bitcoin self-installer instead of qt. The installation failed for some reason so I  uninstalled the self-installer and installed the bitcoin qt in its place.

Please bare with me as I am not technically adept in terms like "dep", not sure what that is.

I never touched any files.

If I have to reinstall, is there any way to save the previously downloaded blockchain? I am not looking forward to that huge download again.

Thanks deepceleron, you are very nice to help and I appreciate your time and energy.

The wallet and blockchain are stored in a user data directory, and are not removed when you uninstall the software. It doesn't look "installed" anyway, perhaps you just unzipped some file.

The official download IS an installer, and is located here: http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.6/bitcoin-0.8.6-win32-setup.exe/download

If this problem persists, you should make a copy of the wallet file (if you have used it for anything), it is located at %appdata%\Bitcoin\ and is called wallet.dat. Copy it only after Bitcoin is completely closed.

Then start Bitcoin with the command to rebuild the wallet. Press WindowsKey + R, and type in:
c:\Program Files (x86)\Bitcoin\bitcoin-qt.exe -salvagewallet  (remove the (x86) if you are on 32-bit windows)

If this is a new wallet with nothing of importance, you can just rename the old wallet.dat file, and Bitcoin will make a new blank file when it restarts.

Hi Deepceleron,

The official gives a choice in wallets. There is an 'exe' and a 'zip'.

Originally I downloaded the exe and it failed for some reason so I downloaded the zip and ran it. You can view this here:
http://bitcoin.org/en/download

Yes, the wallet is empty so no worries there.

Thanks so much, I will try your suggestions and let you know how it went.

Regards, kjo
