Calibre is installed but does not work anymore

[regislnd]

Hello the community, happy to join,
I am under Windows 11, I installed Calibre like 10 days ago, all worked well, i could get the ebooks loaded on it, tranfered to my Kindle parperwhite. Life was great.
But since 2 days, i cannot launch it anymore. I looked at all my Windows defender details, I have an Orange protection suite too on the PC with my mobile contract, but as far as i cant see, nothing seems to lock the application so I missed something.
i look into other users case, they tried also via the Calibre portbale app, i did it, but did not solve anything. Any Good idea?
By the way, be kind in your response as I am not a professional of computer science so to use simple vocabulary will help and my English command is far from perfection too ;-).
Enjoy the day
Regis

I have the same problem i think...
since yesterday i can open it, but if i want to add a book into the library or send to my paperwhite: no response.
And it took a long while before i can close it. task manager? Nope, doesn't help. ALT+F4, Nope, the same.

I don't know if someone will answer u who have more ideas, but for me i found zamzar.com, an online converter. works well for me if no one cares about us here.

have a nice day.

Sumi ^^

Double (active) security is probably not a great idea.
Unless you visit dodgy sites, Defender does the daily job.

Not to say, you can't MANUALLY run other scans., just not have both in control.

Some suites insert themselves into the Mail streams (trying to stop your system if a Bot uses it to spew mails).

No one has deleted anything. You have opened no new threads as far as I can see; you've only posted in already opened threads. You can see all your posts by clicking on your username and selecting "Find more posts...".

As far as I can tell, you have posted 3 messages, none of which were thread starters. One is the one I'm responding to, the other 2 complained about calibre freezing/not working. Your message are rather confusing since there has not been a 32 bit version of calibre since v5.44.0 over 2 years ago. To me, it sounds more as if your computer is having problems. Does Task Manager show high CPU/memory/etc.?

since yesterday Calibre doesn't work anymore. Both versions 32bit and 64bit.
i can start it, but nothing more. Freeze with no response anymore.

Yeah, duplicate security (double, triple, or even more) is a bad idea. Especially when you have multiple ones active. Then you can end up with the AV part of the security recognizing the other security as harmful if not careful. That and some security also use firewalls and multiple firewalls is also a bad thing if they are not matched up. Sometimes eve if they are matched up.

Thankfully Windows disables Defender (and Windows Firewall) if another security package is installed, but they can be turned back on. But to do that is a bad idea.

So long as Defender is kept up to date, as well as the Security Intelligence for it, then that will usually be fine for most things.
