"FileNotFoundError" Calibre doesn't start

[LittleZombie]

Hello guys,

i wanted to start calibre today after maybe 3(?) weeks of not using it. But it didn't start. I tryed uninstalling and reinstalling it, but nothing changed. On reddit i read, that deleting the folders with calibre in /appdata/local and /appdata/roaming. I uninstalled calibre, did that, restarted the pc and than reinstall. Again nothing is happening.

calibre-debug -g gave me this message:

Why does calibre not creat this folders anew ? And how can I force it to do so?


Friendly greetings

[kovidgoyal]

That is the system call to create those folders that is failing. Make sure

C:\Users\wolfg\AppData\Roaming

exists and has correct permissions

[LittleZombie]

The folder exist, but what permission for the folder do you mean? Every other program can write new folders in there. And if I manually create the missing folders it wants to acces the file "global-atomic-_h7f0zqn".
I am really clueless, but thanks for the quick reply

[kovidgoyal]

Then you have something on your computer interfering with calibre, reboot in safe mode and it will likely work, to confirm.

[LittleZombie]

It worked in save mode and the missing folders are finally back, but when I start it in regular mode, I get the message:

"calibre, version 7.17.0
FEHLER: Kann keinen temporären Ordner erzeugen: Kann keinen temporären Ordner erzeugen, Calibre kann nicht gestartet werden "Details anzeigen" anklicken für weitere Informationen."

I followed the instructions in this post, but with no effect.

After I changed the temp directory, it first seemed to be working, but than I got this message:

So i tryed to reinstall again and now I'm back to:

I tryed Safe Mode again and it still works there. But in regular mode I´m stuck with this message. It seems that another program/utility/service somehow blocks calibre from working corectly, but I can't find the right one. And the last changes I made on my PC since the last time calibre was working, were setting up a Ubuntu USB boot drive and the installation of the ecosia browser, which I have already uninstalled.


But I don't have to use calibre that much, for now I can use it in safe mode and I won't reset my windows just for that. If you have more input I would be glad, but it`s not urgent.


Thanks for your help

@LittleZombie if you have an antivirus program running turn it off and see if calibre works. That is usually the problem.

If that's not the problem, turn off everything that starts with your system one-by-one until you find which program is causing the problem.You do have to reboot between turning off a program from starting.

[LittleZombie]

@JSWolf
I already tried that.
But now I did it again and somehow this time it worked. And after turning everything on again it still works.
Don't ask me why, but thanks.

Best regards
