Why do I get this weird error?

[Evin]

Oddly, Calibre gives me this error the second day after I download it. First day it is fine. Second day gives me this error and won't do anything. Third day I reloaded (an update) and it worked fine. Fourth day, I get the error again.

Here it is:
attempt to write a readonly database RemoteTraceback (most recent call last): File "calibre\library\sqlite.pyo", line 119, in run OperationalError: attempt to write a readonly database
Detailed traceback:
Traceback (most recent call last):
File "calibre\gui2\add.pyo", line 62, in metadata_delivered

DatabaseException: attempt to write a readonly database
RemoteTraceback (most recent call last):

OperationalError: attempt to write a readonly database


What does it mean? How do I get it to stop? Is it something I'm doing?

It means whatever user you are running under does not have write permission to the Calibre metadata.db file. You should carefully check your permissions to that file.

Your calibre library folder is owned by the administrator on your computer. Either change its ownership to your normal user acoount or run calibre as administrator

But I AM the administrator. However, I apparently am not a very clever one, as I don't really know what you mean.

This is my home computer running Vista.

How do I change the ownership of the library folder?

You are but your not. That is the magic [sic] of User Account Control (UAC). Where did you put your calibre library? You should be putting it in your users home folder to which you should have full permission. If you put it in the root of c:\ or in program files you will have a problem.

That seems to have done it. Thank you kindly for the advice.

i'm getting the same message but i have my library in my external harddrive since i don't want to risk losing it for xyz reason, so can I ignore it or do I have to put it in my documents anyway?
