fkuehner · 01-18-2018, 09:11 AM

Hi there,

this minday i still was able to ad books to my local Calibre libraryusing my W10 Notebook, now suddenly i am not able anymore. Trying to ad new books resilts in an error like this ( sorry, its german ):

calibre, version 3.15.0
FEHLER: Hinzufügen der Bücher nicht möglich: Hinzufügen jeglicher Bücher fehlgeschlagen. "Details anzeigen" anklicken für weitere Informationen.

Failed to start worker process
Traceback (most recent call last):
File "site-packages\calibre\utils\ipc\pool.py", line 201, in start_worker
File "site-packages\calibre\utils\ipc\pool.py", line 189, in create_worker
File "site-packages\calibre\utils\ipc\pool.py", line 73, in start_worker
File "site-packages\calibre\utils\ipc\simple_worker.py", line 166, in start_pipe_worker
File "subprocess.py", line 711, in __init__
File "subprocess.py", line 959, in _execute_child
WindowsError: [Error 2] Das System kann die angegebene Datei nicht finden

I already tried to recreate the DB but that did not change things.

Anything obvious i miss ?

Your antivirus is blocking the worker process calibre uses to show file dialogs. Most likely it has quarantined some files from the calibre installation directory.

Damn, youre right , Malwarebytes has quarantined calibre-parallel.exe as "Malware.Ransom.Agent.Generic" ;-(

Thanks for quick response !!!

Calibre works good in Safe Mode..

Windows 10 64 bit
Kaspersky Antivirus ( have turn it off but reader will still not open)
windows defender???

It's nothing to do with Windows Defender. I use it with Windows 10. What you need to do now is disable every program and ever service that runs when you boot Windows that is not part of Windows. You need to do this one by one. Disable, reboot, try Calibre and repeat until Calibre works. Once you know what software is causing the problem, you can delete it.

Just an update...

Calibre is working
I'm pretty sure it was Acronis True image
I'm up and running again
