I'm stymied, I don't know how to proceed.
I would be very grateful for any help.
Thank you.
If you are not running Windows 10 64bit or better, calibre will no longer install. One of the basic parts of calibre is QT and calibre 6 uses QT6 which is not available in a 32 bit version.

Another possibility is permission errors. If you are running Windows 10 64bit or better, try right-clicking on the calibre installer and selecting Run as administrator.
