Calibre shuts down after opening

Onemack · 09-23-2020, 05:47 PM

Having been a prolific user of Calibre for many years, I am somewhat perturbed to find that I cannot open it. The program shuts down as soon as the flash screen shows up.
I am using the latest version
I am using it on Windows10 64 bit
I have uninstalled it completely using Revo uninstaller and re-installed it twice
I have gone back to a restore point on Windows 10 two weeks prior when it was working OK

The upshot is that I now do not have access to my library of ePub and Kindle books.

Can anyone out there assist me please

John

What AV are you using? If it's not Windows Security, stop it from running as it could be causing the problem.

If that's not it, rename the configuration directory and run Calibre. If it works, something in your configuration directory is the problem.

If neither works, try safe mode.

It's not just minimizing to the task bar, is it?

Stopped updating years ago and it still works strong.

It is running Windows Security

I don't know what you mean by rename the configuration directory, I assume its not something I do from within Calibre, because I cant open it

safe mode makes no difference, it still wont run

Thanks Kovid,
I am a little further advanced, but I seem to have lost all my books.
The message in safe mode was

"The library database at C:\Users\John's\Onedrive\Documents\Calbre Library appears to be corrupted. Do you want calibre to try and rebuild it automatically? The rebuild may not be completely successful. If you say No, a new empty calibre library will be created."

I said Yes and then got the following message

"Restoring database failed ... Traceback (most recent call last): ... Fail "site-packages\calibre\db\restore.py", line129, in run Exception: Something bad happened"

So I went back and tried again but clicked No this time and got a fully functioning calibre, but with no books.

Have I lost then forever I know they exist in the cloud somewhere! What to do next?? apart from panic???

Here is your problem:
The library database at C:\Users\John's\Onedrive\Documents\Calbre Library

DO NOT put your library on onedrive.

You need to search your onedrive for your books, I always disable onedrive.

And chalk up another "but it worked for years" person who finally had the NAS/Cloud come back and bite them.

I would have thought that a prolific user would have been aware of this issue already. It does make me wonder how many users of calibre, prolific or otherwise, ever check out the forums?

Make sure your new library is your local hard drive, and then import books from the OneDrive location. You will have lost any metadata changes you made in calibre.

Or read the FAQ?
(Remember when installation disks also had 'README' files? FAQ and MR forum stickies should be the first things read when looking for a new app

)

It would be nice to have helpful suggestions for the OP, rather than more posts pointing out where they went wrong.

For example, does anyone know if it could be possible to recover a corrupt calibre database with third-party tools?

The OP might try moving (copy) the entire Library folder to a locally attached (USB or built in) drive, then start Calibre with the option

Quote:

calibre.exe --with-library

Use the library located at the specified path.

Then run the maintenance (if the original, DB exists or do the Recover process using the CLI

calibre-debug [options]
.
--reinitialize-db

Re-initialize the sqlite calibre database at the specified path. Useful to recover from db corruption.

Thanks for that advice, at least I now know how to proceed.

It is far better to receive clear concise useful advice like that, than it is to receive carping, holier than though, advice from people who lecture from on high, as to what I ought have done, or should have known, or should have read.

Do try what theducks suggests. They are far more familiar with calibre than me.
