Calibre not opening

[glename]

I'm not good in computers and also a newbie in using Calibre.
I've tried safe mode,run Admin.
also tried calibre-debug -g

and this is the result


C:\Windows\system32>calibre-debug -g

Uninstall, delete C:\\Program Files\\Calibre2
(or wherever you chose to install calibre). Then re-install. And
dont worry, uninstalling will not affect your books/settings.

did not work
even downloaded a new Calibre msi still did not work
I'm on an old windows 10 pro that has been recently formatted

What is with the weird paths in your initial log?

Is your system environment really messed up?

From a command prompt, type SET
various paths should look similar (just your user logon and a different value than zzzzz's

I tried installing Calibre on a different folder cause it won't run before I made this thread, it was what someone on this site in a thread of someone who have/had a similar problem to mine said to try.

Why is your command prompt showing:
C:\Windows\system32>

It normally should be your logon home:
C:\Users\thedu>

That's because he opened it as admin.

Is the OP installing as a 'admin user' and not as ADMIN?

I meant he opened CMD as ADMIN. That's why the prompt is showing 'C:\Windows\system32>'.

Probably because he had Windows create a taskbar or desktop shortcut for cmd.exe, which for reasons best know to itself sets the starting folder to c:\windows\system32. I recall changing my taskbar cmd shortcut to start at c:\

The 'Windows + x' shortcut menu also does the same. If you choose just to 'Open Command Prompt', then you get your home dir, but if you choose 'Open Command Prompt (Admin)', then you get 'C:\Windows\system32'.

Probably some third party AV - MacAfee, Nortons, Kaspesky, AVG(rief) are all a waste of space.

Calibre worked after updating windows to 20h2
