A fatal error occured

[davyseal]

Hello,

   Every time I shut bitcoin core down and try to restart I get:

"A fatal error occurred. Bitcoin can no longer continue safely and will quit."

EXCEPTION: N5boost12interprocess22interprocess_exceptionE
Access is denied.
C:\Program Files\Bitcoin-qt.exe in Runaaway exception.

I save my wallet, download the software and reinstall it starts up again downloads the block chain, I have tried putting the block chain in the directory from the torrent file and first start up fine, but if I try to shut down and re start I get the error.  Please let me know what I am doing wrong or how to fix it, please dumb it down I am a beginner at this.

Thanks

are you running the program as administrator ?

Have you tried to reboot your computer? It is possible that another process (torrent?) has locked some file required for bitcoin. Another possible reason for the problem is that your anti virus software prevents access to some bitcoin files.

In another topic with the same issue, OP apparently solved the problem by adjusting permissions:

Never mind... all I had to do to fix it was change the ownership of the .bitcoin directory and its contents so it's owned by user, and not by root.

In the other topic the operating system was Linux , in this topic op has problems with Windows.

This could be a number of problems, many of which are unrelated to the wallet software you are running. This happens with windows a lot.

You're right, but it could be a similar problem as it looks like the user has the qt installed in C:\Program Files.

Did you ever get this fixed?

I think this error is related to the .lock file in the data directory.

To open the data directory, go to Start -> Run, then type in:

Code:

%appdata%\Bitcoin

If there is a .lock file in this folder, delete it. If this doesn't help, as others have already mentioned there might be a permissions problem with the directory. Go up one level, then right click on the Bitcoin directory, then click properties. Click on the Security tab, then click Advanced. You should have three lines listed that look something like this (a different order is OK):

Type	Name	Permission	Inherited From
Allow	SYSTEM	Full control	Anything but <not inherited>
Allow	Administrator	Full control	Anything but <not inherited>
Allow	Your_Username	Full control	Anything but <not inherited>

Also, if you click on the Owner tab, next to Current Owner you should have Your_Username listed. If any of this is different, it might be the source of the problem.
