Install problem

jeremiawuzza · 06-14-2021, 08:01 AM

Trying to upgrade Calibre to calibre-64bit-5.21.0
Downloads, installs, reboot but it won't run.
Runs 3.42 when I start it from desktop link
Says 3.42 in lower left of window and update found 5.2.1 in lower right

System W10
there are two Calibre's installed - one in Program Files (X86)
and one in Program Files
the one on Program Files won't run
What should I do?

You simply have both 32 bit and 64 bit versions installed (a valid configuration BUT only if they are BOTH 5.x).
The BOTH use the same Library and settings BUT SHOULD NEVER BE RUN TOGETHER (the reason they now need to be 5.x)

You should uninstall the x86 version as it is NOW incompatible with the 5x library.

BUT Simply remove the shortcut from the desktop, then launch Calibre 64bit from the start Menu (then you should right click the taskbar and create a new desktop shortcut
