Hi,

Unable to open Calibre

As usual, going to folder & running from .exe file or from its shortcut, same I have been doing since 10 yrs.

Well, I have 6456:

Microsoft Windows [Version 10.0.19045.6456]

I got a similar error the other day; this had never happened until recently when I updated Windows to this version.

But it seems to have self-healed; I've been running several instances of calibre portable for plugin development, and they're working fine.

What do you suggest, should I wait or any troubleshoot can be done?

Have you tried installing fresh portable into another directory, then moving the library and settings from current location into this new folder?
