Calibre 7.5.1 won't launch

Hello,

I've tried launching the last Calibre version on Windows 10 after updating, like usual, but it won't launch. (I've tried from pretty much anywhere I could think of)

If I try opening an epub in the viewer, I get the same result. It looks like it was open but the window never shows anywhere (and it's not hidden somewhere weird, I've looked).

I've tried turning off my computer and re-downloading the file and asking it to 'repair' in the menu (and re-tried turning off the computer) a few time in a few different ways, but with no success.

I'd like to avoid uninstalling Calibre because it's always a pain to reset everything, and I haven't made a save in a long time. (I have a lot of personnal column and display rules)

Usually, I just wait for the next update when it does that, but I'm going on vacation tomorrow and I was hoping to be able to update everything before then.

Thank you in advance for any help.

Uninstall LEAVES the Library and configuration.
If you delete a borked configuration (in %appdata%, that will be created (as it was initially) and all you lose are your plugins and their settings.

Is anything calibre showing in Task Manager?

Try booting in safe mode and see what happens.

Instead of uninstalling then reinstalling (which is indeed harmless), you could try this:

- right click on Calibre msi installer
- select 'Repair'

Or just double-click the installer again, click next -> Repair button

No, or I can't see anything at least.

How do I boot in safe mode without access to Calibre? Do I need to boot my computer itself in safe mode?

select 'Repair'
I already tried this a few times, rebooting my computer in-between, it doesn't change anything.

Yes, you boot the computer into safe mode and then run calibre.

I'm sorry, I ended up going away without access to my computer.

I've since then tried to boot my computer in safe mode, and it doesn't change anything.
It looks like Calibre is opening, but no windows appear and nothing shows up in the task manager.

I really have no idea why it happens, and what to try next, especially since I seem to be the only one...
