Just updated to 3.6, now Calibre won't open!

Kraftwerk · 08-04-2017, 12:54 PM

I just updated to Version 3.6 64 bit but it won't open and a error appears on screen.

Calibre runs on a Windows 8.1 64 bit laptop.

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/plugins/settings.

Thank you for replying.

I am no computer expert, so I want to make sure I don't do anything wrong.
My 'Calibre2' folder is as you stated above:
C:\\Program Files\\Calibre2

You want me to delete the whole folder called 'Calibre2', or do you also mean that I could uninstall the current version I have of Calibre, and then install Version 3.6?

Uninstall the current version
delete the folder Calibre2
re-install.
