Have you checked if it's still running in the task manager?

Is there anything in the last logs at %APPDATA%\Bitcoin\debug.log?

Not running in task manager.

The only logs in debug are from when I ran bitcoind briefly to see if that ran (which it did).

Where did you download the bitcoin core? Make sure that you download the core from official website from here https://bitcoin.org/en/download

Can you try to uninstall and reinstall the core? Before you do that make sure you have backup wallet.dat if you have a wallet created before.

Try a clean install (backup first, then delete and purge all old files from install location, esp wallet.dat). Exact same problem happened to me before on Windows 10 Home (installation worked, but client could never execute, without details in error log). I never found out why it happened, but deleting old wallet files and old data files worked for me.

Uninstalled bitcoin and cleared out the files in /Roaming

Re-downloaded from bitcoin.org to be sure.

Clean install and the same issue. Blue circle spins for a few seconds, then nothing.

Very frustrating!

Now that you've started from scratch the log would be very helpful.

Also, have you tried looking in the Windows Error Log?

Have a look in the "Event Viewer", and under the "Windows Logs" section, check the "Application", "System" and "Security" logs... There might be something showing there.

It seems like it might be some weird Windows permissions error... possibly relating to either the install location or the data directory.

Can you try this method below I just found it in bitcoin github while searching this kind of issue.

Can you start Bitcoin-Qt.exe with --resetguisettings?

Start "cmd.exe"
cd to your bitcoin-qt.exe install directory
Enter bitcoin-qt.exe --resetguisettings

If this method still doesn't work try to send this issue on their github from here https://github.com/bitcoin/bitcoin/issues

Thanks dude. Tried this, no joy. Checked the windows logs and same application error is occurring.

Thanks for looking though.

No debug file in the usual place. I guess because it never even loaded it didn't create it?

Are you absolutely certain that your antivirus software and Windows Defender are both disabled?

Do you have the correct bit version for your operating system? A 64 bit program won't run on a 32 bit system (although 32 bit will run on a 64 bit system).

Yes just double-checked.

64 bit system. Avast turned off. Defender off.

I tried searching for the error codes which I posted above but didn't turn up anything very helpful. They seem to general application error codes.

I just went the whole hog and uninstalled Avast (this old PC was only meant to be a full node so not risking much)… no joy...

Can you try running bitcoin-qt with the -debug -printtoconsole options from a CMD?

Command line options reference: https://en.bitcoin.it/wiki/Running_Bitcoin

[Pmalek]

Windows Defender can be a bit tricky to turn off. Here is a guide how to permanently disable Windows Defender just in case you want to do that.

Question... I assume you have already tried restarting the computer? It's possible there is a ghost process somewhere screwing things up and preventing it from starting properly.

To be honest, I'm really clutching at straws here

The only other things that I can think of are:
- Permissions problem with Windows... was it an upgrade of an existing installation of Windows? or a clean install of Windows 10 on a formatted drive?
- Corrupt Windows install and Windows is missing some libraries/dlls or something like that.

Like I said, clutching at straws...

Have restarted a number of times.

I think you may have hit on something..

It was an upgrade from Windows 7 to Windows 10. I think that perhaps it might be missing some dlls because Win7 was playing up so I thought I would upgrade to Win 10 which would solve the problem. Would there be some existing dlls which wouldn't be replaced/upgraded by Win10? If so, how would I go about fixing them?

Many thanks for your help.
